We thoroughly enjoyed Isabel's Studio. It's even better than we expected! Isabel and her staff are very punctual in communication and check-in was perfect. The Studio is very very central, we were a bit worried about the noise of the "movida" :) but instead, it's an island of quiet and peace in the heart of the city (a few steps away from Sol Plaza). It's clean, beautiful, well equipped, everything is new, very high quality and good taste. Couldn't choose better for our stay in Madrid!
