The hotel was SENSATIONAL IN EVERY SENSE!!!!! I was kindly greeted by JESUS from the night shift, who was very polite and enthusiastic and helpful. As son as I arrived he gave me maps of the city. He was always in good humor (not like in other cities I went to). ALMA from the morning shift was GREAT GREAT GREAT!!!!! She helped me in so many ways with metro information, touristic information, she told me how to get everywhere and even helped with my luggage (which is also not common). KELBYS and ALDAIR were always present around the lobby, chill out rooms or terrace to help me and solve my doubts. The TERRACE of the hotel is like feeling in PARADISE!!!!! It´s really unbelievable: NEVER SEEN A TERRACE LIKE THAT IN MY LIFE!!!! It had a bar, where you could also eat. It was FULL of places to sit (like small living rooms) and to socialize with other people. It had sun umbrellas and its wall were painted very cheerfully (I will put some pictures now). It even had 2 jacuzzis which were not in use because of the weather (it was COLD). Great music. The hotel organized great events for every day. The dorms were INCREDIBLE: each one had it's own sink, toilette and shower (all separated). There were aldo showers in the hallways (which I sometime used when I got up too early not to make noice). EVERYTHING WAS SO CLEAN AND SPOTLESS!!!! Women were cleaning all the time. The people I met in my dorm (THERE ARE ALSO INDIVIDUAL ROOMS) were great. I don´t know if they located tourists from similar region coutries inentionally, but (I am from Argentina), there were mostly Mexicans, Brazilians and Argentineans, who have a lot in common culturally. AND ONE OF THE BEST THINGS FOR THE END: ITS LOCATION WAS PERFECTTTT!!!!! Half a block away from The Gran Vía, near to the best shops and walking distance to Madrid´s principal touristic attractions. I bought a metro ticket which I nearly didn´t use. I WOULD DEFINETELY STAY AGAIN IN THE GENERATOR ON MY NEXT TRIP!!!!!

THERE IS NOTHING THAT I DIDN´T LIKE OR COULD HAVE BEEN BETTER

A really cool and funky hostel! I was really impressed with the aesthetics of the accommodation. The roof top bar was amazing! Great drinks and a lovely place to spend the evening. Brilliant location, walking distance to so many restaurants and beauty spots.

The staff were very temperamental. Some staff looked like they really didn't want to be there and came across very aloof and unapproachable. Kudos to Nick from Miami who made an effort to come and chat to us. Other staff please take note. It really doesn't hurt to acknowledge guests and give them a smile once in a while! Also, a shame the hot tubs were out of use.

Great location, clean comfortable room (4 pple) with private bathroom, curtains / outlet / light, private storage under bed, place to hang out downstairs and also a rooftop bar that you could hang out.

Locker storage system, had to pay for storing luggage after checkout. And it was confusing, you had to select the number of the locker & size and pay in advance, I ended up choosing one too small and couldn't change after, had to go to the reception, but they refunded me. Expensive drinks in the rooftop (5 eur a wine glass) and didn't feel a community vibe, was more if you already had a group.

Staff and location

No stand in the toilet. Nice design but not pratical. Toilet in the room for 8 persons,we got not enough tissue. I inform a cleaner, she says yes she will... but the 2nd night we even having less. The box with the locker under the beds bunk are horrible, it makes a loud noise. For sure it depends on the user how they are so careful or do with good manner or not. But as i experienced they are not. Better recommend the guest at the check in time; a short brief about manner for not making loud noise.if possible.

Profesional, helpful, and lovely receptionist. Easy to access the rooms. Good bed management. Close to grocery's, main roads, and many others. Clean/fresh bed sheets. Cleanliness is taken seriously. Nice Lobby. Muchas Gracias!

Just saw some dust at one spot, but it was not dirtiness. It's not a problem for me, but in the reception in the ceiling just above the receptionists desk, there are the air systems: It's very loud, i can't imagine, and it will not be surprising if receptionists have a headache at the end of their 8-hour shifts. Posibility to put some anti-sound foam!

Location was perfect 👌🏼 Right in the middle of the city, it was easy to move around the city and almost everything on walking distance. My family and I enjoyed the breakfast buffet; basic things but the essential. The lift was very convenient. We asked for transport from the hotel to MAD airport, taxi arrived in 5 minutes with a fixed price of €33; host solved it in a minute and she was very efficient. The room was a bit packed for 4 people, but we only used it to sleep, no biggie. Beds were comfortable, even the bunk bed. Highly recommended!

Rooms are small; it is OK for a few days, though

Location is superb, a few steps away from the Gran via and just a few blocks away from Plaza España, Plaza Mayor, Mercado de San Miguel and several metro stations too. Everything looks clean and new. Shared areas (especially the bar at the rooftop) are very nice.

I stayed on a 4-bed room that was indeed a bit on the smaller side. Like other reviews mention, there is no shampoo or soap available inside the shower BUT you can find that next to the sink outside it. I found a bit weird that my floor had separate showers but no bathrooms, so if the bathroom at your room is occupied, only thing left to do is wait patiently.

The location is excellent. The metro is nearby, but you can do a lot on foot. It's next to Gran Via. I stayed in a shared room, but the bed comfort was excellent. The hostel is very organized, and the breakfast is well served.

When I went, there was a school trip happening, which sometimes caused shouting in the hallways, and people spoke a bit loudly in the common areas. However, I wouldn't take this into account too much as it was a one-off situation. What disappointed me the most was the rooftop. I thought it would be a place where everyone could relax at will, but I realized that if you don't consume anything at the bar, it's not quite like that. And when the bar isn't open, it stays somewhat closed. As a result, there isn't much common area to stay in. In my case, the common areas always had children shouting, haha.

Generator Hostel is a very straightforward, super well organised Hostel right in the city center. In a female dorm of 8, you get a bed and a locker, there is space to put your things on either a coat hanger or a shelf, and there is a shared toilet+sink+shower in the room. That's a perfect basis! You can also buy everything you need at the reception: flipflops, earplugs, showergel, which came in super handy!

Being right in the city center means that the streets can be a bit loud at times, although the windows do an ok job at isolating sound. The room and bed were clean, mostly also because the guests seemed to take super good care of being tidy and clean. It could have needed a thorough scrubdown for the little details, but thats me being very very picky and the rotation of guests doesn't really allow it I think. On the last day, I left my luggage in the common lockerroom, which costs 4-6€.

Great Location, Great Value for the Price! Easy access. My room (Family room) was with a view on inside garden, so it was pretty quiet there.

Not much to say, but at one night there was a drunk visitor making much noise in entrance (probably the football fan after Madrid vs Stuttgart game), shouting an hitting at the doors and it lasted more than half an hour in the middle of the night. Someone (guest of the hotel) let this guy quiet.
