We spent a month in Sylvia's apartment and for our first experience with my wife and daughter in Madrid it could not have been better. The apartment is even more impressive in person. Sylvia had the kindness to provide us with a small bed for our daughter which was really nice. Decoration is top notch by the way. The location is so central that you have easily access to metro, bus, shops, famous Plaza del Sol. Sylvia was away in vacation when we arrived but made sure in anticipation that we were properly welcomed by Marie. She was always reachable. I truly recommend her apartment, a great experience.
