This is a good place, close to everything but removed enough not be noisy. It is clean, the linens were clean, etc. The terrace is great if you are in Seville at the right time.
It is on the ground floor though and the walls are paper thin so you hear everyone coming in and leaving, which can be inconvenient late at night or very early in the morning.
If you have a late flight out of Seville, you may not be able to leave your luggage anywhere in the building unless there is no one checking in after you. This is despite the fact that the entire building is owned by the same host and there are spaces other than the apartments. This won't affect everyone, of course, but it is something to keep in mind. There is a luggage locker service nearby called Easiday.
