We had a great stay in Buenos Aires and the apartment is a wonderful base for exploration of the city. We were welcomed by a friend but did not meet Valeria until we checked out, the check in was easy. She had left her sube card which was very helpful and we used this a couple of times. The house is just on the edges of Palermo and not Central as listed. However, if you are happy to walk it is perfect. A short walk away and there are lots of bars and restaurants.
