This place is great. Central location is convenient to everything the Old Town has to offer. Jaime has put a lot of thought into the residence, including a much appreciated umbrella, excellent kitchen accoutrements, singularly appropriate art and furniture, and a comfortable bed. There were maps, texts of "must do" opportunities, help with early check in, and more.
Be sure to go DOWN the street as well, instead of just up to the Old Town--many more unexpectedly terrific cafes, bakeries, shops, stores, and things the tourists don't normally frequent.
If you are visiting Valencia, this is the place to stay.
