The apartment is really well located and well equipped. We were within walking distance from lots of main touristic spots in Seville, there were plenty of restaurants, coffee shops and bars around.
The check in was easy and they were kind enough to let us come into the apartment 1 hour before the official check in time.
As other reviews noted, it can be quite noisy. It's only really a problem in one of the bedrooms, which seems to be right above a very busy pub, but it wasn't an issue in the rest of the apartment.
I'd definitely recommend this property and stay there again.
