I stayed in a really great hostel in Buenos Aires (which I have already mentioned in one of my other reviews).
This hostel was easy to book online, and being a large hostel they had space even up until the last minute, which was good.
The staff were very friendly and welcoming, and did everything that they could to make me (and the other guests) feel welcome and comfortable.
The hostel was cleaned every day, and, unlike in some places, the cleaning staff were also very friendly and did not make you feel like you were getting in their way all the time, or were just a nuisance travller. I even talked to one of the cleaning staff about some of the best bars in town, and she was quick to recommend some excellent places- and happy to do so also.
I thought that there were not really enough computers for such a big hostel, and I think that this is something that they could improve.
The hostel was well located, very close to the Subte stop, and in a nice part of town. The directions on the booking site were also good.
This is a place I would be happy to return to!
