My husband and I stayed at Christians place for 2 nights. The apartment was spacious and clean. We could not meet Christian because he was travelling for work, but we met his aunt who gave us a very warm welcome and handed over the keys. We dont speak spanish, so she used her phone application to translate everything for us and made sure we were all comfortable. The apartment is pretty close to Chueca metro line, makes it easy to travel around Madrid. So, overall the apartment is great and easily accessible by public transportation too. We had a very nice stay!
