This apartment is an add-on structure, atop the roof of a house. Although it seemed permanent from the pictures, there is no insulation between this flat and the one below. So, on the enclosed patio in particular, you can hear everything the guests in the flat below (same owners) are saying. In addition, the the triangle pyramid roof seen in the photos actually has windows along the bottom--that also open up into your flat. So you can hear their conversation from there as well! It's coming from all sides. Of course it's disruptive, but mostly embarrassing to hear everything that is going on word for word. And I had to assume they could hear everything I was saying and doing also! Lastly, each time the front door metal gate opens and self-shuts, the slamming sound travels up the echoey stairs, directly into this flat--so this will happen all night long as other guests in the building enjoy Sevilla nightlife. If you plan to go out all night, or don't mind having your conversations heard, or listening to others', this flat is otherwise very clean and tidy. The response of the owner was very disappointing, however. I accepted the loss on the first night, but asked for a refund for the second, and left. Their response was "we have asked the people below to be quiet. The problem is solved." The problem was never the other guests; they were just enjoying themselves, in a very reasonable manner. The problem is that this was actually a shack built on top of a roof.
