First things first, this is NOT a Hostel, it's a night club. BsAs has so many options of bars, pubs and clubs (free entrance) that I can't get this people that prefer party inside a hostel.
I stayed for a week and in general there was only weird people hosted there, they stayed at the hostel the whole day.
Almost all the staff are rude.
The male staff are always chasing after girls. There's only one person in the reception at time, what makes you wait a lot sometimes. There were two recepcionist that seemed to be drunk and high all the time.
The owner Maurice is always around or at the bar, he's kinda nice, but it's creepy that and old guy living in a party. He always try to fix the bad things his staff do or say, but he's the one who hire this dumb backpackers to save money!
The bar is 24h and has rooms in front of it, lucky of me it wasn't mine. At the bottom of the building it is a club at weekends, the music seems to be inside of our room and it shakes the whole building. I stayed a week and I didn't sleep well not even a night.
It's not aloud to smoke (only at the bar and terrace), but everybody does, the owner as well.
This hostel is really dirty, they don't have enough bathrooms and at the end of the day it looks worst than a club toilet. The water in the showers keep going from really hot to ice cold.
I was there at winter, the heat is ok, but there's no condition air and no windows at the rooms, makes it smelly and it must be a hell in summer.
I just recommend for people who want to live inside a party, don't wanna sleep and don't wanna go outside to know the city!
The only good thing about this hostel is the location.
