The whole team was very helpful and friendly. They were very responsive to any questions or requests we had. We stayed at several different apartments in the same building as we were traveling around Argentina and were using Buenos Aires as our "base".
Really liked the fruits and water that they left in the room. Also, the location was excellent for going anywhere in the city. Just beware that depending on which apartment you get, you may or may not hear the nose. This particular one was facing the inner courtyard so it was very quiet.
