The house is very good, especially the host is very hospitable: he offered us spaces in the kitchen for storing our food, he hasn't limited us the access to any of the areas in the house; he even gave us a bus card and the chance to recharge it for us (very useful!!), plus other little things (discounts for the bio parc, a beach umbrella, fresh water at our arrival etc.) that made our staying in his flat more confortable.
The bedrooms are clean, there is a mini fridge and a fan too. The kitchen is ok, there was everithing we needed but the counter and the dishes were a bit oily (for us it was no problem, as we washed the dishes before using them). He offers the living room as a place where to eat because it has a table with chairs; however the hosts smokes in that room with closed windows cause of the air conditioning, so it can be a bit though for non-smokers.
The neighbour is a bit distant from the city center and the beach, but it's filled with bus stops through which you can reach every corner of València. It also has plenty of markets and cheap places where to eat or take away the food.
In conclusion me and my friends stayed well in Vincent's flat, and I would recommend it, especially to young people who don't care much about the conditions described before.
