I am looking for a reasonably priced place to stay in Buenos Aires. I would consider a B&B, private hostel room, or hotel, but I am doubtful about an apartment, as I would prefer a little more sociability. A convenient location is a primary consideration.

I found this thread, but things may have changed in 2.5 years, and people may have more suggestions.

Here are a couple of places I have found. The problem with these is that I am not sure they are convenient areas. I have the feeling it would be good to be very close to a subway station. Giorgio's House is close, but seems far out. Noster Bayres seems to be on bus routes.

Any places you have really liked? I can speak some Spanish.
