The apartment has a fantastic location near to almost every single thing you could possibly want to see in Sevilla, Jose Luis was very nice and gave us some pointers and suggestions on restaurants and landmarks. There is also a binder that has some really good suggestions for restaurants, you sometimes just need to book in advance.
We did have a problem on the way out, we followed the instructions regarding check out, but apparently someone floated the door to the building and we ended up being trapped without being able to get back into the apartment and not being able to exit the building. Fortunately this was at 7 am so after waking half the binding a Neighbour was gracious enough to let us out. So just make sure that the door is open before leaving the keys at the apartment on the way out. Not the hosts fault but probably a better system is needed
