We stayed at Francisco's place for 6 nights. It's located a 5 minute walk from the Bulnes subway stop in Palermo. We found most of the sights in Buenos Aires to be conveniently located near stops on this subway line. Several beautiful parks are located within a 2 to 15 minute walk from his place. Francisco, and his parents, who me met were great resources and lots of help with Buenos Aires information. They also had subway cards we could borrow, making it easy to expedite getting around. His place is in a secure building and has everything you need. I would stay here again and recommend it to other guests.
