We had a great stay at Quim and Isabel's apartment. It was clean, the a/c worked great (and was needed), the beds were comfortable and the water pressure was great in the showers. Isabel greeted us with fresh baked bread, even though we arrived an hour early from our red eye.
We couldn't have asked for a better location -- we walked everywhere -- the museums, the Atocha train station for our day trip to Toledo, Sol and Plaza Mayor.
Highly recommend!
