Raul was the best! Very cordial and all smiles. He lugged my heavy suitcase upstairs and even woke up early the day I left to bring it back down for me!
When I got there, he showed me maps and train info. He had breakfast for me each day. His place is 4 flights up and 6 minutes from the Renfe and 15 from the metro by foot. I definitely recommend staying with him :)
