We had a wonderful time staying in Marta Y Javier's apartment. The space is really stylish and comfortable, the rooms were big and the amenities were perfect for a long weekend in Madrid for a couple of friends. Everything was very clean when we arrived and the communication was perfect - we were even able to check in a little early which was really helpful! The area is really nice and just up Calle Atocha are some really nice boutique shops, and tavernas. Reina Sofia Museum is also a very short walk across the road, and further down the street are some beautiful parks. The bus to the airport is a 5-10 minute walk, but you are also very close to metro stations. I would highly recommend staying here.
