The apartment is really fine. Tiny, but right in the city center so it's very easy to move around Seville. It looks just like on the pictures. Maybe I can add that it's a little dark because it's located on the ground floor, which in Seville is an advantage - it helps to keep the space cool.
It looked like the entire building is rented to tourists or at least a lot of apartments. Everyone was calm so we didn't have any problems with the neighbours.
The only thing that bothered me a little was that the apartment belongs to Pepa (at least that is what it's stated here, on AirBnB), but I had to contact someone else for check-in and then a third person was actually there when we arrived - a girl that didn't know much about the apartment.
Apart of that, our stay was spotless. Thank you. :)
