I staid 2 days in Ana's apartment with my gf. It was kind of a last minute booking so most of the other options were unavailable.

pro: great location, not far from aeroparque airport, and cloth from palermo and plaza italia. Ana is a kind host and was very accomaditing as we arrived sooner that expected. We had Quilmes in the fridge which was a nice attention.

con: really noisy (works in progress, loud music at night), the apartment is kind of dark (no sunlight at all comes in) and a strong painting smells that might give you some headaches. Not a very welcoming place to live.

To sum it up, I would only recommend Ana's apartment as a last minute option, as with time, you will find way better option on the same budget. However, I would recommend Ana as a host.
