We stayed in Carmen's beautiful apartment for some months and we can say that we felt like home. Also the balconies are great to enjoy a nice view over the charming streets of Madrid. The kitchen is well equipped and everything was clean. Carmen is available whenever a problem occurs and helps immediately to solve it. The location is perfect - you are in 2 minutes at the Puerta del Sol. We really enjoyed our stay and want to say thank you to Carmen at this point!
