Guadalupe 15 is a great place with helpful communicative hosts. The very family friendly apartment was more than big enough for our family of 3. Pool is shallow but super refreshing on a hot August day. Beds very comfortable, has everything you need. Despite being a building with many short stay apartments it's very quiet and still feels private. Great location within easy walk of all the main attractions and, in the other direction, the mainline rail station, supermarket and great restaurant options within 5 minute walk. Really great! The only negative was there was some building works happening on the roof lounge area and given the heat, work started at 07:00 so it was tough to sleep late, but that was a small annoyance in the grand scheme of things. This is a great option for exploring Seville and highly recommended.
