This apartment was close to many of the sites we wanted to see in Madrid so that was convenient. It is small but it had everything we needed to be comfortable. Sergio helped us locate a business where we were able to store our luggage until it was time to check in. The apartment is near the Tirso de Molina subway stop so it's easy to access. Although I don't think the neighborhood is great, there is a locked door into the building and then two more locked doors so we felt safe.
