The apartment was excellent. It is located near the bull ring in a quiet part of the city centre so a quiet nights sleep is possible, but is within 5 minutes walk of cathedral, alcazar and other sites so very well located.
Apartment itself is very spacious, could easily accommodate 6 people and was clean and very nice.
Miguel the owner gave very clear & helpful instructions. He also repaired a damaged a/c unit within 48 hours.
Overall, highly rate Seville, the apartment and the owner.
