Christian Y Felix's beautiful apartment was just what we were looking for. It is so well designed and comfortable and in such a great location that our stay there was one of our best. And they were so kind to help us will some little problems of our own and they went out of their way to make us feel at home. The location was perfect for us. Restaurants and shops were within a few minutes of the apartment-- some even on the same street-- and markets for food shopping, bakeries, and pastry shops were close by. The sites and sounds of Madrid-- the museums, El Rastro flea market, Retiro park, all within such easy reach. I highly recommend this unique space and these special hosts.
