We had a great stay with Sergio! He is a great host who was quick in his communication. The flat was very spacious and comfortable. We were a family of 4 with two teenagers and felt everyone had a lot of privacy. The large terrace also offered great views over the Atocha area of Madrid. Location was excellent and we were across the street from the Atocha station, which was perfect for us, as we left on the AVE train the next day. Great value! Highly recommend!
