This could be a 5 star stay for some people but unfortunately for us we found it too noisy at night. If noise doesn't bother you then the apartment itself is very nice and modern, with 2 balconies and rooftop terrace and is close to the metro station 1-2 stops from the main tourist sights. The local area is a bir rundown and graffiti'd but we didn't have any problems with the location. The hosts seemed very friendly and were happy to offer recommendations of what see etc.
As for the noise, we arrived on a Tuesday and found the music from the nearby clubs and bars was too loud to sleep properly even with earplugs and closed windows, and this carried on until 6 am, at which point the clubs close but the room was very light as the blinds let a lot of light through. Although the noise level varied each night music is normally on until 4-6am. We found that sleeping on the sofa bed downstairs was quieter and we were able to sleep okay there, but ideally we'd rather have slept in the bedroom.
Overall, this apartment would be great for people less bothered by noise, but for us we would have to choose somewhere else to stay to sleep comfortably.
