Sylvia was very nice, was there when we arrived, gave us all of the information for the apartment, and gave us good advice about the neighborhood, etc. She also gave us an extra set of keys to the apartment, which was very convenient for three people with different schedules and interest. The apartment is wonderful, lots of extra things to make it feel homey. It was especially nice that there was enough hot water. The neighborhood is great. We really loved Retiro Park, and walked through and around it everyday. It is also close enough to all of the sights to walk, metro, bus or cab without spending too much time getting to places. I would stay in Sylvia's apartment again if I'm lucky enough to go back to beautiful Madrid.
