Carlos and Victoria are very responsive to my messages and emails. They are also very well-detailed for directions as to how to get into the apartment, which is a plus. When our AC did not work, they immediately fixed the problem for us. In addition, the location is excellent. We can walk to all of the touristy spots by foot! On the other hand, the apartment is extremely loud. We can hear whenever the door opens and closes, when people pass by, the neighbors next door, and every little thing because it is on the first floor right by the main door. If you are sensitive to noise like we are, this may not be the place for you. All in all, it is a pleasant place to stay at for a few days in Madrid if you want a place for convenience.
