Alessandra's place is fantastic. We stayed three months in her apartment (my wife and our two children of 4 and 2 years old) and we had an excellent experience. We came because of work, but we also looked for a place from where we could enjoy Madrid.
The apartment is precisely as it looks in the photos: nice, very well equipped, comfortable and cozy. It is second floor with street view (Santa Engracia). Although the street is usually noisy, the apartment has double windows that fully protect from the noise.
The location is also outstanding: there are 4 metro stations from 3 different lines (1, 2 & 7) a few blocks from the apartment. The neighborhood is family friendly, safe, but also fun (nice tapa's restaurants and coffee shops, specially at Ponzano, Santa Engracia and García Paredes, the wonderful Sorolla museum, beautiful squares such as plaza Pablo de Olavide and Chamberi square, ecc.) and convenient (there are stores, little markets: bakery, fruit-vegetables, local products, fish, cheese, ecc.).
Finally, Alessandra is a wonderful hostess. She was always quick to answer and attend any request. And beyond anything related to the apartment she was always willing to help us with all kind of guidance and information that help us settle in Madrid.
