Vivien's apartment is a great place to stay when visiting Valencia, loads of cafes and bars and markets in the local area and great transport links to all the major sites (including the beach, aquarium and easy access to airport).
We are a family with a 16 month old baby and so having the travelcot and high chair was great. The flat itself was good for our baby to run around (not too much to break!), he loved the balcony and looking out on the happenings below. We, the parents, enjoyed the balcony off the main bedroom of an evening for a glass of wine, peaceful. Also having use of a dishwasher and washing machine made life a lot easier.
On reading a previous review there was a comment regarding the aircon and the flat not having aircon in the bedrooms which is accurate however, for us, the fans provided by Vivien were more than adequate - the temperature whilst we were there was 26-29 degrees, maybe at hotter times of year it might be an issue but it wasn't for us.
