Isaac & Jose's apartment (we were in touch with the latter) is a pleasent place above the buzzing city of Valencia. The location in the middle of Ruzafa is just perfect. Everything you need is a 10 minute walk max. The aminities in the apartment come handy and the terrace is lovely.
Sleeping upstairs can be difficult as the AC is not able to cool the entire place down. We missed the iron, which might as well fit in the apartment.
Jose, the host was responsive and flexible in terms of our arrival time, but we missed some local knowledge and tips about the city.
