Our stay at Cristina's apartment was wonderful. The apartment is even more gorgeous in person than in the online photos. It is located in a fantastic, convenient, and safe location. It is literally across the street from Atocha station, which made it so easy to use Madrid's fantastic public transportation system. There are also 2 train lines that run directly from the airport to Atocha station - making it simple and extremely cheap to get to and from the airport. The check-in process was smooth and Bárbara provided us with helpful tips regarding restaurants in the area. The apartment was clean and offered all of the amenities you need and more (i.e.- hair dryer, steamer, microwave, fridge, stove top, Brita water pitcher, extra toilet paper, etc.). I would 100% recommend this apartment!
