There were some issues with my check in but I think the team was well intentioned although disorganized. I had to wait alone in the hall for several minutes before someone came, even though I had given a lot of headway about the time of my arrival.
When the person finally showed up, everything was fine and he was really pleasant. They rent several apartments so this one is only used by travellers. I had no issues with the small kitchen, although there were no cleaning products available.
The neighborhood is actually perfect: you feel like a local in a small pedestrian street with no tourists in an area with easy pedestrian access to central Seville.
I probably would not have rented this apartment if I had known there was no wifi. There are plenty of wifi opportunities nearby, but you still have to find them and still would not provide constant connexion.
