Josefina is a wonderful host who clearly cares about her guests' comfort & safety. She was always quick to respond to questions & to offer help.
Her apartment is very charming, comfortable & well-kept. It was a welcome reprieve during my first few hectic days in Argentina. The balcony was an especially nice feature.
While it's perfectly located to easily access many major sites on foot, the immediate area is lacking the charm of some other neighborhoods. For the better bars & restaurants you definitely have to head elsewhere in the evenings, easy enough to do though with the cheap taxis!
