Be very careful about following the rules. We accidentally missed the section about prohibited access the upper floors and used the upstairs kitchen to wash our fruits. Mercedes was very angry with us, threatening to contact Airbnb. A misunderstanding led her to believe that we broke the rule again (which we didn't) and I ended up spending a good hour or two doing damage control and explaining the situation to Airbnb. It was our fault that we missed reading the rules, but it also wasn't communicated to us at check-in. We thought Mercedes' response was too severe considering our transgression, and the stress was an unnecessary damper to our trip. We also would have appreciated more direct communication - she would greet us in person like everything is normal, but then send a strongly worded message on Airbnb minutes later. I would have liked to solve any issues openly and directly.
The house itself is fine. It's situated within walking distance from the main sights and it has old Sevillian charm. Just make sure to read all rules clearly before you go.
