Not you traditional Hostel, individual rooms with in suite shower. I decided to give a shot for a two week Argentine trip. Great location, safe neighborhood, good dining options a short walk away. Room is small but functional, comfortable bed. Bathroom is tiny, with an even smaller shower. While tidy and neat, room needs a good deep cleaning. I stayed on the first level and noise from outside was very noticeable with windows closed. Fortunately the area is fairly quiet at night, with only traffic sounds entering the room.
No social activities you would typically associate with a hostel, which for me was a plus. I just needed a room to sleep in, and this for the bill. With such a low per night rate, I booked the room for 2 weeks straight. Even though my travels had me outside Buenos Aires for several days.
I would consider again when visiting the area
