We had a very nice stay in Ruth's apartment. The Prado museum is 10-15 min. away on foot, and the Reina Sofia museum is literally right around the corner from the apartment and so is the Madrid central train station. There are small supermarkets open in the daytime on the street and restaruants and late night shops in the evening.
Ruth is very fast to respons and is very helpfull if you have any questions. So we enjoyed our stay very much and can give Ruth and the apartment our varmest recommdndations
