Alison's apartment is in a great location. Every main attraction was walkable and we didn't use the car at all for the 3 days we were there. Sevilla was at the tail end of our road trip around Spain and we were able to find free street parking nearby.
The apartment itself is about a 4 out of 5 but great value considering the location & cost. It can use a coat of paint and the hand soap in the bathroom was watered down.
As for Alison as a host, she was very communicative although we never met her since she was out of town. We were greeted by her cleaner. She was very strict on the check in time. We were delayed by 40 minutes (by the time we found parking and located the house with our bags) which became a minor issue since the cleaner had been waiting to give us the keys.
Overall a good experience.
