Great location, you are close to the historic center and to a lot of bars and restaurants. Even if you are in a very busy street, the apartment is facing an interior courtyard so it’s very quiet. However the apartment isn’t well isolated so you can hear the neighbors but it wasn’t an issue for us.
The communication with the host was very easy and he was really quick to respond to all our demands. It was also really easy to get and leave the keys.
We had a great time in Valencia. We recommend!!
