My three girlfriends and I stayed here for a 3-night stay in Sevilla. The property was gorgeous and very authentic. Location wasn't in the middle of things, but a very close walk to all the action (and very quiet which was super nice). The apartment itself wasn't huge, but it was great having two bathrooms and a kitchen/living room area. The pool on the first floor was a nice spot to relax after a long day of sightseeing.
The hosts were very welcoming and communicative. Our AC unit was leaking the first night and they took care of it the very next day.
Overall I would recommend this apartment for your stay in Sevilla!
