It was a lovely and economical flat to stay in. Everything was clean and comfortable. One of Sergio's friends met us promptly at the front of the apartment, and let us in. He explained most things to us. We would definitely recommend staying here. It is a block or two away from the Metro, so you have easy access to all of Madrid. The only problem we encountered was that there was no toilet paper, but there was a bidet that we had an interesting time learning how to use. 5/5
