Hi!

Me and my family came from Puerto Rico and Laura received us and showed us the apartment personally. It was in excellent conditions, very clean and spacious. We think is the best location available for a tourist in Madrid. Is in the center of La Gran Via which is the main avenue of the center of the city. Every place you wish to visit is walking distance, places like Plaza de Sol, Calle Mayor, Plaza Mayor, Plaza Espana, Palacio Real, the Cathedral, Templo de Debod, El Prado Museum, ect, ect, ect.
We took a tour bus to Toledo and the place of departure was in the same block of the apartment! You can also take a bus tour to Segovia from the same spot.
Transportation won't be an issue, take a taxi from the airport and then use the Metro (Subway) in case you want to go far, but you wont need it because everything is walking distance.

Bottom line, is the best place you can choose. We had a great time, in part because of the apartment. We'll definitely come again.

Thanks Laura!
