We enjoyed staying at Sylvia's apartment - it is very close to both Retiro Park and a metro station. The apartment was quiet and spacious - we enjoyed exploring the area - it is also close to the public library where we went with our child. Sylvia has made the apartment particularly kid friendly by providing a drawer full of toys and some nice picture books to enjoy. Despite the apartment overlooking the street, we found it quiet at night (the master bedroom faces the inside of the building & is away from the street). Overall, the apartment was perfect for us & Sylvia was responsive when we needed to communicate with her.
