We had a lovely stay in Madrid in this apartment. Vanessa was very helpful and was always contactable if we needed anything, the directions given on how to get from the airport were clear and direct. The apartment was clean, light and had a lovely view of the street below entering into Plaza Mayor. It was extremely central, so that we could literally walk everywhere. There are quite a few flights of stairs to get up to the apartment with no lift, but this is very normal for Spain.
Overall we loved our stay here and we would definitely recommend it, particularly if you would like to stay in a central location.
