We spent a week in Buenos Aires in this small effeciency apartment, and it was just like the photos show. It is in a terrific location to Plaza Dorrego, the Sunday market and many fine cafés in San Telmo. The small patio makes the place what it is though. Great for listening to the Tango music wafting in from the Plaza below. Mariano (host) was very nice and always super quick in response to our emailed questions during our stay.
The only qualm would be a slightly uncomfortable bed. And if there had been an option of a fan over the AC, that would have been nice. Otherwise, we had a great stay!
