While Luis' apartment is centrally located and convenient to the city center, our room was small and cramped. The bedroom door did not have a lock, and even though there was a closet inside the room with a chain and lock to secure our belongings, I did not find this to be a sufficient security measure. If you're looking for a place to crash for the night that's close to things to do in Madrid, then a room in Luis' apartment will suffice; however, I would not recommend this for extended trips or a vacation for couples.
