This is a beautiful flat with an absolutely stunning view from the roof terrace, exactly as pictured (as others have explained, it is not accessible directly from the flat itself). It's very stylish, again just as in the photos. There is noise from the bar on the roof terrace, although it didn't bother me particularly. There is no noise from the flat because of extremely good triple glazing on the windows, and I found the bed very comfy. I loved my stay here, and would be very happy to visit again. Seville itself is wonderful.
The check-in process was handled by Mila, who was just lovely, and who spoke really excellent English. She sorted out a proto-issue with the aircon very quickly.
At present the host provides nothing by way of consumables in the flat, except for a welcome bottle of wine. Although this was a lovely touch, I'd have swapped it for some coffee, sugar, salt and oil, and it's unusual not to have anything left at all in the flat. It's not as though there aren't supermarkets or restaurants nearby, it's just a bit annoying to buy things that are only going to get used once or twice.
I stayed here by myself. It's perfect for up to two people, I'd have said. Although there's a sofa bed so technically the apartment sleeps four, you'd need to know each other pretty well, as you have to walk past the bottom of the bed to get to the bathroom!
Communication was very good. I always have excellent experiences from my airbnb finds, and this was no exception.
