We had a lovely 4 night stay in the apartment. Susana was unable to meet us when we arrived, which was no problem for us as she sent really detailed instructions with pictures and videos which made letting ourselves in really easy.
Susana was really helpful sending us lots of recommendations of things to see and places to eat. She even gave us information about the local parades as we were staying on Three Kings Day.
The main sights are very easily walkable, and there are lots of shops and restaurants close by.
I highly recommend this apartment if you are coming to Seville for a short break.
The bus from the airport was very easy and a bargain at €4 each, again Susana provided the information in advance.
