Javier is a very nice and welcoming host. He answers quickly on any questions and helps you to get from the airport to the house with easy-to-follow directions. It is a short walk from the metro station, easy to do with suitcases. He welcomes you with a map and a lot of information about Madrid and surrounding places and will be happy to tell you what to visit if you like. He is happy to answer questions but also gives you as much privacy as you want.
Most important, the room, kitchen and bathroom are very clean! Cleanier than a some hotels I have stayed in in Spain. I recommend staying here for sure. If I was a girl alone I wouldn't be sure if I would like to stay in the neighborhood, but then again I guess a lot of the alleys in Madrid are scary if you are alone.
The bed is also much better than most hotels in this price range!
Very much recommend, we had a great stay!
