Inmaculada is a very nice host. They picked us from Sevilla airport(A service they offer for a fee and if they have free time) and mentioned several things we could do in Sevilla. The apartment is in a romantic old building at the centre of Sevilla, within 15 minutes walking distance of pretty much all the tourist spots(Except maybe the Sevilla 1929 expo site but you can also get there walking). The apartment also has many tourist service provider booklets. I felt the area is very safe and quiet, but I'd make sure I have a map, because the historical centre of Sevilla can be quite confusing for a tourist.
