Great secure place in walking distance to train, Plaza Mayor, the Prado, and Park Retiro. I believe the building is a mixed use space (commercial & residential), but there was a doorman to allow/monitor access to the building, which made me feel safe. Good food close by, and would suggest speaking to a local to get food recommendations. I found the better places to eat were cafes/restos off the beaten path and not included in the 'Check-In' Book/Guide provided in the apartment. The Hosts were nice, responsive and informative about transport. The apartment is located just off of a pretty busy street, the bedroom and living-room windows face that busy street, so in the mornings I heard the bustling of the city/car horns/buses passing/people talking, which did wake me a few times. If you're a heavy sleeper - it should be no problem. All-in-all great place.
