Francisco was a fantastic host. He was there to show me the apartment as well as providing a tour and recommendations for the surrounding area, and also provided two SUBE cards for the week for convenience to ride the subways.
The apartment is located in a great part of town, right across the street from a park and easily accessible to the trendy neighborhoods of Palermo and Recoleta. The place was clean and beautifully set up, and I really enjoyed my stay. The only issue I had was that the Wifi was occasionally slow or hard to connect to, but that was a minor inconvenience for an otherwise great stay. I would definitely recommend this apartment for anyone looking for a convenient home base for their Buenos Aires visit.
