Me and my partner stayed at Alvaro's apartment for five nights and we really enjoyed it. Alvaro was very easy to communicate with and he was very helpful. Even though our plane was delayed, and we arrived late at night, he still took his time to welcome us and give us a lot of tips about what to do in Madrid. The apartment is located in what is probably the most interesting area in Madrid, with lots of cosy bars and restaurants and close to all the main attractions. We really recommend staying at Alvaro's place!
