The apartment at Calle Cuenca 2 was situated perfectly outside of the hustle & bustle of old town whilst remaining at walking distance from the more popular attractions in the city center and jogging/walking distance from the Túria park. There were plenty of great food and coffee places nearby such as Bar Cassalla (excellent destination for foodies) or El Pederniz. Be aware that the apartment is situated on the 4th floor and does not have elevator access, so make sure to not bring too much luggage with you on your visit.
Communication with the owner (Raphael) was great, and he was incredibly responsive. Requests for small fixes were immediately acted upon and he was also very gracious after we accidentally broke one of his wine glasses. Overall, we would definitely recommend you to stay at Calle Cuenca 2, whether you intend to keep up your running habit or whether you're more into having incredibly great food.
