Me and my boyfriend had an amazing time in Valencia and in the apartment. We spent 8 nights in Ignacio's apartment. Everything was perfect and everything was there: airco, WiFi, towels, shampoo, enough cutlery, plates and so on. The place is not very big, but definitely big enough for two.
Ignacio's son gave us the key and explained us some stuff. Didn't have to wait for him, he was already there when we arrived.
In short terms, great place to stay during your stay in Valencia.
