Leonardo was a great host, and although we didn't meet him, he was easy to communicate, gave lots of information and tips, and his partner Victor met us and answered all our questions.
The apartment is beautiful and has anything you need, inc. coffee machine.
The location could not be better - we were right on Plaza Mayor and 5 min. walk from the royal palace, in an area full of restaurants, bars and coffee shops.
In summary - highly recommended!
