We were a group of 5, staying for the first time in Madrid, for 2 nights. The apartment is easy to find, being close to the main train station and a metro at the end of the street. It is very well located for most major tourist activities. We were met by our friendly host who gave us clear instructions and answered all our questions in English. Also, previous communications were all responded to very quickly.
The apartment is well furnished and absolutely spotless, especially the two bathrooms. It is exactly as described, and in a pleasant and safe neighbourhood, 10 minutes stroll from Retiro Park.
We were all extremely happy with the experience, and would be happy to use the apartment again.
