Vin's apartment is a compact treasure! It's furnished at the same time in an elegant and comfortable way and located conveniently in a quiet neighbourhood however within walking distance to main art museums (Reina Sofia, Prado, Thyssen-B.) and to good public transport connections (Atocha stations nearby). Vin himself was very helpful and clear in his communication. We had no problems during our five nights' stay in the apartment and we do highly recommend Vin's place. Thank you, Vin, for letting us feel at home in Madrid!
P.S. The stone floor is gorgeous and feels great to feet after the heat...
