I spent 3 sleepless nights because of doors slamming really loudly every 2 to 4 minutes, except for the time between 1:30 am and 5:00 am. Talking to the receptionist I was promised that the loudest of these doors would be fixed the next day; it wasn't. Bathrooms were not particularly clean, for sure not as clean as those in German or Dutch hostels charging about half of the same rate per night. No power socket for a hairdryer in the bathroom. I would recommend you to stay elsewhere.
The beds are too high compared to those in other hostels!! It was almost dangerous to climb to the top level, the whole bed shook and seemed quite unstable. And I only weigh 55 kg., not 100... Otherwise very nice.
The best hostel I have stayed at so far. Excellent breakfast!
