I would stay here again for the location alone. Walking distance to nightlife, shopping, restaurants, and my favorite...the botanical gardens that are two blocks away. Cute neighborhood, and felt very safe. The Apartment unit was nothing special, but was exactly as advertised. My friend and I were only staying two nights in Buenos Aires, so we weren't at the apartment much at all except to sleep. Basic amenities, but being able to do laundry was the biggest perk.
Communication with the hosts was great, and they were kind enough to welcome my friend and I with a bottle of wine.
The place was simple, not glamorous, but a fine place to rest your head for the night.
My only complaints being that the keys to the door took some time to figure out, the hallway outside the unit smells like cigarettes, and the same hallway is a little eerie at night with there being no light on in the hallway when you get home at night. You have to turn the button on in the hallway after exiting the elevator.
