Gustavo is great. Our flight delay for 9 hours. (From Barcelona to Madrid air Europa) and we arrived Madrid very late night 11:50pm. Gustavo wait for us to open the door for us. And love the simple deign of the house and the kitchen set is awesome. We had the most awesome coffee in the morning made by Gustavo's mocha coffee maker. The neighborhood is very quiet and the location is great. You can visit all the important museum by just walking around.
