Pleasant 4-star hotel which is about a 10-minute walk from the train station. Rooms were well-equipped and well-kept, and service was friendly and efficient.
Great location is very convenient, not only for the train station, but for all the local sights within walking distance. Keep in mind that Valencia is a city that seems to come to life as soon as the sun goes down ... it's almost as you're in a different city entirely in the daytime.
The only negative was only a temporary one ... during my stay there were repainting the walls of the hallways, so there were barriers all over the place, and sheets of plastic covering the carpets.
But apart from that minor temporary inconvenience, this is a nice convenient place for a short stay in Valencia.
