This apartment is very central and very close to the cathedral in Seville, but once you're inside - you wouldn't know it. We visited during Easter, when the celebrations go on nearly all night - we weren't disturbed by noise, but when we stepped out onto the street we were in the middle of everything.
The apartment looks just like the photos, and was spotlessly clean. We didn't have a lot of need to contact the hosts once we were there, but the communication in advance of our trip was really good - prompt and helpful.
When we come back to Seville, which I'm sure we will, we'll be staying here again. Top marks!
