I stayed in Cristina's apartment in La Latina with my daughter. Cristina was an excellent hostess. She's very organized and has thought about all the details. The communication was also great. The apartment is really outstanding. The apartment is on a top floor and has amazing views from three balconies over the rooftops of Madrid! It's actually quite spacious by European standards. The bedrooms have the amazing view of the city. The kitchen and bathroom are in he back of the apartment and have some minor views. The kitchen and bath are a bit small, but very functional. The decor is simple and traditional from Spanish apartments with all the amenities. The location is superb, in a great area right in the center of Madrid. The Metro La Latina is just a few steps from the building, and you can walk to all the main sights in 10-15 minutes (Plaza Mayor, Reina Sofia museum, Royal Palace, etc). The Latina area is really a very trendy area with restaurants, nice bars and plazas right in the middle of the city. The apartment is literally across one of Madrid's largest markets, where you can get all kinds of local and gourmet goodies. The area is safe and really bustling with people day and night, it's not necessarily noisy or crowded, but there's definitively a lot of activity (not for the quite type!). Highly recommended for 4-6 people or a family.
