Great apartment in a great location with a very responsive and helpful host.
We stayed for a week in Salvador’s apartment and it worked very well for us. We enjoyed the light filled kitchen/living space and the quiet bedroom. Yes there are stairs but we knew this and it did not bother us. The surrounding area is great for bars and restaurants as well as nearby metro stations although we tended to walk everywhere ourselves.
Salvador himself was very responsive to all our questions. I would stay here again if I was back in Madrid.
