We stayed two nights in Seville and the apartment was excellent for our stay. It is close enough to the city center in order to walk there, it is nicely decorated and well equipped, it is located in a quiet area with bars and supermarket nearby and the parking space was a nice extra. All the maps and brochures in the apartment were very helpful as well.
Alfredo was very welcoming and he has given us lot's of recommendations where to go to and what to see. He also was quite flexible regarding the time of the check in.
All in all it was a pleasant stay and I recommend this apartment to anyone who wants to visit Seville.
