Juan's apt was clean, in a quiet zone. The Real Alcazar was just 5-10 minutes by walk from the apt. Juan and Olga, Juan's assistant, were very kind (there were a welcome gift at the arrive and the last days they let us to keep our luggages at home before the ckeck-out time) and easy to contact. Olga welcomed us and gave us a city maps and some helpful advices.
We slept very very well (it's not easy to find good mattresses). We were a group of friends and we found everything we need in the apt.
Strongly recommanded for friends and family, too.
