I really enjoyed my stay with Julio. He is a terrific host and shared some wonderful knowledge of Madrid with me.
His place is in a great location, very close to the Palacio Real with easy access to the subway system. I love to walk and I found it very easy to walk to all the major attractions that I wanted to see. There are many restaurants very close to him and if you like nightlife than this is a good place to be...lots of bars!
After being out all day sightseeing, I loved coming home each day to his comfy attic room. I was travelling alone so it was nice to have someone to share experiences with...almost like being part of a family. The wifi was good, the bed was comfortable and even though it is on a major street, I found it quite quiet. My only caution would be to say that it is not what I consider a bed and breakfast.
I highly recommend staying with Julio and if I ever get back to Madrid I would certainly be happy to stay with him again.
