I stayed at Rocio's place in Palermo for a long weekend.
The unit has access to a pool, two comfortable beds, a bathroom, and a small kitchen.
It's steps away from great food options, parks, markets, etc – It took about an hour's walk from the apt. to el Obelisco de Buenos Aires... if you're into long walks. Bus and subway are also close by.
Rocio is a wonderful host. Everything was clean and ready for us to use. We felt very comfortable in the apt. She was always a message away to help get us acquainted with the neighborhood and the city in general.
This is a great find, take it if you have the chance.
