My parents really enjoyed Sevilla. The area around the flat is very active and typical spanish with lots of little cafes and restaurants. To the actual tourist things it is a 15 minutes walk. So that is fine as well.
The flat had everything which was needed and was very clean and modern! On the photos it seemed a lot bigger than it was though.. Also we thought it is more light in the flat but the windows in the living room go into the courtyard. The bathroom is very modern and the shower really nice :) For 2 Adults the bed was a little small but in general the flat is totally fine and from the rooftop you have a great view and can enjoy a glass of wine perfectly while the sun goes down. The communication with Christina was very good and always when we needed something she was available, you could tell that she is renting the flat often.
So enjoy your trip to beautiful Sevilla!! :)
