I have stayed at Ariel's room on two separate occasions for several days each time. The location of his apartment is right in the center of downtown Madrid and everything is within walking distance. The room is clean and nicely furnished and the set up of the apartment allows for a lot of privacy and separation of living space. I will continue to stay at Ariel's when in Madrid for all of the above reasons and also because \I found Ariel to be a great host. I give Ariel 5 stars.
