Really cool hotel-love the decor and theme. Close to lots of amazing restaurants (especially Vietnamese!), supermarket, bakery, pharmacy, bars, metro station around the corner. Front desk is very friendly and helpful especially the American-Michael:) The room is large enough, comfortable bathroom with heated flooring. The bed was super comfy! We would definitely stay here again when in this part of Berlin!

Breakfast is pricey but convenient and the dining area is lovely.

The hotel was super stylish, the rooms were large and comfortable, would recommend to someone staying for a weekend in the city. Loved the relaxation room at the top of the hotel with the views over the city and the sauna. Close to a tram to easily get around the city.

Whilst the wellness area had herbal teas and fruit there was no tea in the room (only coffee) and as an English tea drinker It would have been great to have a kettle and some tea bags in the room.

This Hotels creates some intriguing hybrid of club-ish vibes meets tropical garden restaurant with thoughtful touches throughout the mazes. Extra nice touches to be guided to the space, very professional and amicable.

There could be a few more info points, but that's not necessarily a negative. Be a discoverer.

It is a great hotel, modern and clean, and the best part was the fantastic rooftop sauna. The room was big enough, and the bathroom, particularly the shower, was luxurious, quiet, and calm. I will return to this hotel when I´m in Berlin next time. I want to give a big thanks to Katja for her kind service.

The quality control of the cleaning staff, otherwise nothing.

The sauna is very comfy. The room was quiet. We got the room at 10am in the morning, since I asked for it. Really appreciated. Gym room is also comfortable. It's near some tramway stations, so it's easy to move in the city.

The lifts didn't work the third day. Not a big deal, but disappointing. It was not very good to have no electrical outlet near the bed (there was some but in the ground). The bathroom is huge. Best would be to have a bigger room and a smaller bathroom. We didn't test the breakfast.

Location of the Hotel is near a Tram Stop - So easy to get to various Stations etc,...and Airport Buffet Breakfast was great - All of a very high quality. Bathroom was excellent with fabulous shower. Access to a Spa area with Sauna etc (although I did not use) looked lovely with robes & slippers a plenty.

The TV in the room was very good but would be good to get access to external Apps - ie Netflix Few channels in English (ie BBC World News :( )

The location was great, easily accessible by tram and walking distance to the Ringbahn. Where sly Berlin really shines is in its design and comfort. The beds were super comfortable and spacious and the in-room amenities were lovely. We loved the key card system that made it nearly impossible to lock yourself out of your room. The breakfast was a bit pricey, but the food was delicious—I loved the custom egg station!

Housekeeping timing was a bit inconsistent, but we can't complain because the housekeeping staff did a great job of cleaning and tidying our room.

Very cool industrial style. Lovely conservatory / bar / dining space. Room was very clean, sound proofed and generally well equipped. Super comfy bed. Close to tram stop and walking distance to a few neighbourhoods. Friendly staff. Good to be able to leave our bags after check out. We enjoyed the spa and view from the rooftop relax space.

Only small things. Slightly far away from main sights, though easy enough to get a tram. Toilet seemed to be constantly flushing through with a constant trickling noise which was annoying, especially at night. No milk in the room. Not the best lighting for getting ready. We stayed for 4 nights but didn’t have our water replenished after the first 2 nights. Possibly a bit cheeky calling it a spa when it’s only a sauna and chill out space.

Because we had to move rooms, and there was a downgrade, staff comped us breakfast for our stay. The breakfasts were magnificent! Made to order Benedicts and omelettes, a wide array of choices for every breakfast taste, and a cheery, bright dining room. The room we downgraded to was not at all noisy. We discovered shower heads on wands. These aren't common in America but they should be. Staff made Berlin much easier for us: they sold us transit day passes and added the costs to the tab. My wife got daily mochas at the bar in the morning (the coffee machine couldn't make them). Breakfast also had carrot juice shots. I have gone on and on - breakfasts were really that good. Had we stayed longer we surely would have taken advantage of the spa deck and exercise room. Modern ambiance coupled with old-world manners (a good thing!). Oh, we had dinner there as well - the dining room really transforms at night. My wife's trout was stellar. My pasta with truffle sauce was only so-so.

Our first room had an air conditioner that sounded like the Luftwaffe. Staff graciously moved us to a street-facing room on the top floor. The new room was under-furnished. We repeatedly requested a second chair and second lamp, but they never showed up.

Lovely place, good location. Across S-bahn and close to Friedrichshain/Kreuzberg and very stylish interior. Room was quiet and good temperature (airco not too cold)

How excellent the hotel is, how disappointed we were in the restaurant. The menu (choose) was very limited and space was too big (lots of empty seats). The starters were not really starters, more bites and appetisers and only three items. Main course was okay but also limited in choice. My suggestion to Sly is to put ca. 5 good sized starters and 5 good sized main courses on the menu with some variety. Meats/fish/veggies/Vega for each and include fries/potato/rice in the main courses.
