We had an amazing stay at Walter's apartment. The apartment is located in a quiet neighbourhood, close the the beach. There's a bus and metro stop just around the corner. There are a lot of restaurants in walking distance and they're very affordable! There are also a couple of supermarkets very close to the apartment.
The apartment itself is very clean, complete and cozy. It has a fridge, washing machine and a balcony to dry your laundry. Every room has a fan, which is radio controlled. The contact with Walter was very pleasant. He offered to pick us up from the airport and brought us back the airport at the end of our trip. That was a nice extra service! Walter also told us about the bike rental, where and how to get bikes. It's so nice the explore the city by bike, especially the Turia Park.
We would definitely recommend this apartment, 10/10! :)
