Most of all, the hosts, Carlos & Cristina, were really friendly people. We had problems with our private matter (i.e., electronic toll problems) and they helped us successfully resolve the problem.
As you can see in the pictures, the house is really clean and lovely. And, the neighbors are also friendly and safe. The metro station is only 5-minute away from the house, and it takes about 15 minutes to get to the city center.
Everything was great!
