Hard to fault. The apartment is in a great location, close enough to the main attractions but far enough away to be quiet. Too many good places to eat within walking distance as well. The apartment is clean and well appointed with one of the best showers I've had while staying in Seville.
Nacho as a host was responsive and made both check in and out as simple as possible.
Would definitely recommend and would be happy to stay there again if the opportunity ever arose again
