Loved the apartment and has everything one needs. We were two adults and found the space quite spacious and functional.
The apartment is close to the Metropol (5 min walk) then the Cathedral (10-15 min walk). If arriving into Seville Santa Just Train station, then bus no. 32 gets you close to the apartment, with only a short walk.
Jose's parents were able to give an overview of everything even with the language barrier (we only spoke English, and they Spanish/French). Jose followed up with a phone call to ensure everything was OK.
