The apartment has been recently converted and is in good condition. It is quiet. It is in Triana, which is over the river from the main town of Sevilla. However it's a short 5-10 minute walk to get to the main city centre, and there is a metro station (the line goes to the main city area) only 1 minute from the flat - although we didn't need to use it. There are supermarkets, other shops within easy reach, a local bar 50m away and a coffee shop slightly further.
Triana is a close suburb of Sevilla, but it feels more like a local area than a busy tourist centre, although there are some places to explore. In Triana, there are lots of good bars and restaurants that mainly cater to locals, but also cater to tourists of course.
In the past we have stayed in Sevilla, but next time we will probably stay in Triana again.
