The apartment is excellent and in a good location - great area for bars and restaurants (feels more local than the touristy areas) and about a 15min walk across the bridge to all of the sights.
We had a bit of an issue with the power on the first day as it kept on flicking off. But we just had to flick the mains on and off to get it back. And it settled down after our first day. So not sure if it was an apartment issue, building issue or area issue.
Only criticism we could find was that responses were hard to get during our stay, and intro information limited. Eg when we had the power issues, where to dispose of rubbish, where to dry clothes etc. Just little things that would have helped.
We enjoyed our stay in Seville - Triana is a lovely area.
