Myself, my wife and our 10 year old daughter stayed here for 17 nights in July.
We loved it. The apartment really is beautifully decorated. It is very new and modern with a nice balcony at the back. It had everything we needed for our stay (modern fully fitted kitchen, large living area, modern bedrooms & bathroom, good Wifi).
The neighbourhood has lots of Chinese restaurants close by and a lovely friendly bakery right beside the apartment. There is also a great market on the street outside the apartment every Tuesday. The neighbourhood felt safe at all times day or night. It's 5 mins walk from the train station and 10 mins from the tourist centre. In the other direction it's 10 mins walk to Russafa where there are many great cafes and restaurants. We also took Bus 19 many days to the beach (the bus stop is 5 mins away and the bus journey is about 20 mins to the beautiful beaches of Las Arenas & Malvarossa).
Overall we had a wonderful holiday. Valencia is a wonderful city, Eino was a great host who made everything simple for us and the apartment was a perfect base for us. We would definitely return without any hestitation.
