We had an absolutely fantastic time at Sergio's apartment! It is a very nice compact loft apartment and has everything that you could possibly need. Sergio was extremely nice and met us at the apartment right when we got off the metro. It is very easy to find the apartment from the Lavapies metro stop after arriving at the Barajas airport, and it is quite close to both grocery stores and a variety of ethnic restaurants. It is in easy walking distance of most of the major sites, so it is perfect for people who enjoy walking as a way of getting to know the city.
