Perfect!
Oscar is a very good host. I had trouble finding the flat.. Having arrived at night, and late. Oscar was so helpful that he took the time to look for a parking spot and even parked for me. After what felt like half an hour, he took the time to patiently explain where the best restaurants were for breakfast, tapas and dinner were (all were very good). He also drew a guide for exploring the important sights of the city. We normally would use Rick Steve's guide or a TripAdvisor guide.. But his suggestions were so good we didn't even use them.
The flat itself is just like the photos and it was very clean and comfortable.
All in all.. A real pleasure.
