Highly recommended. The flat is in a stylish building, is well decorated, and is generously proportioned for two people. The neighborhood is charming; not too touristy but ten minutes away from the historic centre and the bars and clubs. Lots of places to eat and drink within a few minutes walk.
Yolanda was in contact and actively supportive from the day I reserved. Her daughter welcomed us at the flat and provided us with maps and information. They were very accommodating about the check out too.
I organised the stay in Seville as part of a grand tour of Andalusia and this was the best accommodation we stayed in.
