Location is really good, the neighborhood is very walkable and has a lot to offer. From the San Telmo market to the sunday fair, you can find gems to buy. Great places to eat there also, for meat eaters our favorite was Des Nivel and for vegan/vegitarians: Naturaleza Sabia and for pizza: Bar Napoles.
The airbnb however had a few downers: the shower water pressure was not great and the bed is very worn, don't look forward to a great shower or sleep comfort. On the upside the unit is cozy and offers a resident experience.
