We had an enjoyable time in Alicia's apartment. The communication was great throughout. Her partner was there to meet us, and let us in early and explained everything to us. Alicia also had someone come in midweek to clean, change sheets and give fresh towels - we really appreciated that :) We were a family of 4 and were quite comfortable. You couldn't asked for a more central location - close to everything! That being said, Madrid is a city that apparently never sleeps and it got quite noisy even at night, but I suppose that's the trade off for being right in the center of it all. It was very safe, had an elevator, a huge department store and supermarket just steps from the door, as well as shop, and restaurants everywhere. The Tourist Information Booth is right outside with very helpful people and the Sol metro station is just opposite the apartment. We loved Madrid and will be back!
