Aroa's place located at a very strategic place, Ruzafa.
You get what you see in the picture -- the room is amazingly beautiful and the house is stylish too.
The area located at Ruzafa, close to everywhere and in fact, you can walk to the Old Town (Central Market, Palace, Cathedral, Silk Museum, etc). You can take a bus/2 stations away from Xativa (which is 10 mins from her place) to City of Arts and Science. The bus stop to the beach is just a second from the building which is very easy to commute to the beach!!!!!
There are plenty of shops/restaurants in the area so you dont need to worry about that.
Overall, this place is worth to stay for your vacation in Valencia. You (including I) will not regret it!
