The apartment is exactly as in the pictures. Very nice decorated, cozy, clean and with all the needed facilities (wifi, nespresso machine, air con).
Francisco is a great host, he was super nice and helpful. He even prepared a Valencia guide with his favorite spots and local restaurants, which we could use to explore the city (thanks again!).
The location is fantastic! Walking distance to the beach, to the metro and public transportations and in a historical neighbourhood with lots of good tapas places and a nice traditional market. The weather was very nice and we could enjoy breakfast in the balcony (even in February).
Take into account the building has no elevator, and the apartment is in the third floor, so be aware of this.
In general we loved our stay at Francisco's place and I would highly recommend it if you want to visit Valencia!
