Ricardo and Oscar were truly wonderful hosts. I always got very prompt responses to the questions I asked. The apartment is centrally located and walking distance to Royal Palace, Train Station, Plaza Mayor, Plaza del Angel, Plaza del Sol, Gran Via, Prado Museum. Ricardo suggested some really nice restaurants - Vi Cool, Ginger, La Santa Ana, etc. - all of them turned out to be perfect. The apartment is nice and tidy with all the necessary amenities.
We will definitely come back at stay at the apartment (if available) during our next visit to Madrid.
Thank you Ricardo and Oscar for your wonderful hospitality.
