We stayed in Madrid for 4 days and Julio's place was ideal in all ways.
Communication was perfect from the outset and the the apartment itself was easy to find by following Julio's directions.
The location was perfectly central and we found that each of our planned destinations were easily reached, with a great selection of restaurants and bars also near by.
...Not only was our room extremely comfortable, but Julio (and his son) were both wonderful hosts and very knowledgeable about different things to do.
Muchas Gracias Julio!
