Sergio's place is fantastic and he is extremely communicative. The apartment has beautiful natural light - we came with our two children, which meant we had to spend more time inside the apartment, but you almost feel like you are outside in the space. It also is a wonderful walk down the pasillo horizontal - the building itself is an Argentine architectural experience. It is also generally spacious. Sergio helped us in the planning stage as he helped us determine that this was indeed the right place for a family with small kids, and he was very responsive and helpful while we were staying there.
