The pictures accurately describe the vibes and facilities of the hostel. It’s very attractive for anyone visiting Siem Reap, with quick access to the main temples around. There is a large spread of activities and many different travellers. The restaurant and bar serve tasty food, making this place very accommodating. The bathrooms are clean, dorms are tidy and all facilities are inviting. My only purpose was sightseeing of the temples, and I found this hostel perfect for that. Only at the end of my stay did I realise that the name is pronounced Wonders and not O-nuh-durrs (that’s on me).

Depending on one’s privacy preferences, the curtain of the bed only covers half of the beds length. Could be nice to have full curtains.

This was my second stay with Onederz. Hostel is very well located (central to all attractions). Pool and rooftop bar were great with views of the city. Beds were comfortable, clean bathrooms and strong shower. The staff are incredibly kind and helpful. Great tour options from within.

As is the case with Onederz, the "privacy" curtains only cover about a third (maybe less) of your bunk making things a bit awkward. Also WiFi barely worked from my room. Had to keep going downstairs to the common area for service.

This is hands down the best hostel I have ever been to! Staff and check in experience was amazing - we had a private room and they were kind enough to check us in early. The ground floor has a large social area and resturant & bar overlooking the pool. Food options are great and very reasonably priced, as well as the bar. Really beautiful and clean facilities. Multiple pools - the rooftop pool was a vibe with a DJ and bar! We attened a quiz evening, which was well organised. Our room was lovely, and had a small fridge, kettel and free water bottles. The hostel and room smelled lovely too!

No complaints. I wish I could have been there for longer!

Staff were amazing, and couldn't do enough to help. We also did 3 organised tours and all were excellent. The guide for Angkor Wat was very very good and the food tour was very fun. The facilities are good, 3 pools, restaurant, Bar etc. The cooked food is decent at the restaurant, had an amazing salad and some great summer rolls. The bakery stuff like croissants cakes etc is maybe a bit overpriced and average in taste maybe, but general food and drink is good and cheap, and cheap beers, good, cheap cocktails. They put on so many events which is great - yoga, movie night, socials etc. Location is super central. Everything very clean. I stayed in a private room which was good, which even though they had a dj night you couldn't really hear the music as it was far from the bar. I liked that they did events and had a vibe, but it wasn't a party hostel. Easy to meet people but not a ravey place.

The water went off twice which wasn't ideal! Also can be tricky to get sunbeds if you get there too late.

- Location is good. - Both dorms and private rooms are spacious and nice. - Shared bathroom is decent. - A lot of possibilities for booking tours and activities. - The whole place felt very clean. - Restaurant within the hostel has many options and the food is decent. - Multiple swimming pools. - Staff is incredibly nice and helpful.

- The bathroom of my private room had no warm water and a bad smell at times. - Curtains of the dorm bed didn’t close all the way so they didn’t give that much privacy. - It’s a big hostel, so therefore it’s also quite busy, so keep this in mind cause it makes socializing during the activities a bit harder. - Wifi is not always great (randomly stops working). - Housekeeping starts relatively early, which can be annoying if you have a private room and are still getting ready/sleeping in (so always make sure you have the do not disturb sign on the door).

An Unforgettable Stay at Onederz Siem Reap! I had an amazing experience staying at Onederz Siem Reap! The location is perfect—close to everything yet tucked away just enough to feel peaceful. The entire place is spotless, and the cleanliness really stood out from the moment I arrived. What truly made my stay exceptional was the staff. Every single team member was warm, helpful, and went above and beyond to make sure guests were comfortable. Their service is truly top-notch. The hostel has such a great atmosphere—friendly, social, and full of good vibes. There are plenty of activities organized daily, making it easy to meet other travelers and explore Siem Reap together. And let’s not forget the food—absolutely delicious and reasonably priced. I honestly didn’t expect hostel food to be this good! I originally booked just a few nights but ended up extending my stay—that’s how much I loved it here! Whether you’re a solo traveler or with friends, I highly recommend Onederz. It’s more than just a place to stay—it’s an experience.

This was a great hostel. The ground floor/lobby area was big and had different areas to relax in depending on your mood. The pools were big and beautifully designed. The restaurant served delicious food. The hostel has different activities planned each day which made socializing easier. I met some really amazing people that I met up with again in koh rong and Phnom Penh. The front desk was able to book my overnight bus to Sihanoukville and were always so kind when I had questions. I was in the 4 bed female dorm, it was a decent size and the bed was comfortable. The lockers helped keep things organized and minimize clutter. The showers were big and had shampoo and body wash.

The bathroom was HUMID! I hated coming out of the shower and immediately sweating. There was a rotating fan that faced the mirrors and sink but even that didn’t help bc it was just more hot air circulating. The bed privacy curtains were only half way which was odd Maybe a me problem but the outlet next to the bed was too high. I had to put stuff under so my plug wouldn’t fall out of the socket Have to put a deposit for a towel in addition to the check in deposit and you only get it back once you return the towel. This means if you leave the towel on the bed and forget when you check out, you won’t get the towel deposit back. Once you check out, they will only give you the check in deposit as there is no way for them to know if you rented a towel too.

All staff were absolutely amazing throughout our stay and go out of their way to help you. They are so welcoming and friendly and you get a smile/hello everywhere you go! Bar/restaurant area is a nice place to socialise and is very reasonably priced for the quality of the food and drink. We ended up eating there most days as it was just so good, especially the Japanese menu! Dorms could be improved slightly. I was nearest to the door and the A/C didn’t reach me so I woke up sweating every night. The doors are also really loud so expect to be woken up. The pools are nice areas to chill at but get there relatively early to secure a lounger!

The Oneserz in Siem Reap is a great place to stay. I stayed in the Annex in a private room and it was nicer than some guesthouses I’ve stayed in. Modern, clean and comfy and the Annex even had its own pool in addition to the two pools in the main building. The communal space was really nicely and spacious, and the food in the restaurant was really good - lots of variety, reasonable and tasty. They even offer an early morning breakfast buffet for those doing the sunrise Angkor Wat tour. It’s a really social place and there is something going on every day that you can get involved with. Their sunset cycle tour was particularly good fun, and special mention (and big thank you) to Nita and Dara who were our guides that afternoon. Because that is the main draw of the Onederz in Siem Reap - the staff. Everyone (and I mean everyone - from the reception team, to the restaurant staff and the cleaners) were so friendly and helpful. The reception team always have a smile on their faces and are always so accommodating and go above and beyond to help.

Location was great, private rooms were basic but included everything we needed. The separate pool for private rooms was nice for older travellers who prefer a quieter pool area. The mini fridge, kettle and safe were very nice to have.

The private pool area was often busy with guests not staying in the private rooms. They would use all the loungers and none would be left for private room guests. The laundry did not smell clean when returned and minor stains were not removed from the clothes. The rooms often smelled musty. Just from lack of air flow in the rooms I think.
