We are a 4 people italian family, all adults, and went in Valencia for 4 days on november 2016, spending our holiday on the Edu's flat. It was the third time we used airbnb to find lodging, until now with plenty of satisfaction, and Valencia has not been an exception: hardly we could have done a better choice.
His flat is really bright and comfortable, quite large, delightfully furnished (website photos are perfect), and we stayed nicely in it. Although he could not be present when we arrived (in late night!), his friend gave us the keys and explained clearly all about the apartment: dinner room, the two bedrooms with all the whites, the equipped kitchen and the bathroom with the large shower, not to mention the balcony. Really convenient for its position as well: just 15 mins foot to the ciudad vella - Valencia center.
The apt, that is at third floor, is really quiet and so the neighboorhood: in front of the house there's a little playground for children, and we ate in zone a couple of time and bought some food etc in a convenient supermarket close to the flat. Metro and bus stop are quite near, we used bus 95 to reach Oceanographic in 20 mins or something, and around 10/12 Metro stops to go to the sea. Trips from and to airport were quick and cheap using taxies: 22 euro to arrive, only 15 to go (weird but true).
Edu is very communicative: he answered all our questions and more, before our trip began. At our arrival, we found in the flat a detailed paper written by him with a lot of useful infos about visiting, eating and anything else for enjoying at the best our stay in Valencia. And during holiday he was always available thru messages to help us about anything.
It was like to be a local rather than a guest visitor, and this has no price :)
