Valencia, like Granada, were my two favourite places to visit. Silvia is a lovely person, and made me very welcome indeed. My bedroom was comfortable, and I had my own shelf in the fridge, and access to all amenities, including bathroom, kitchen, living room, dining room, and WiFi.
La Calle Zurradores is a narrow Street in a maze of small narrow streets in a quaint area of Valencia, right in the centre of the old city. What a great location! A few minutes' walk tales you to the city Square, with taxis, tourist buses, local buses, and a large number of restaurants and tourist shops. The railway station is about 15 walking minutes away. The whole area seemed to be quite safe to walk in.

Tourist destinations are easily accessible, and you can reach most of them with a hour of walking, including the Opera house and science museum. The huge harbours de area is easy to reach by bus, and is worth a visit. Check out the old shipyards from the 1600's. Unfortunately, the over-harbour cable car which was heavily advertised, was shut down indefinitely. I spent hours walking there to ride on it, in vain.
I would stay there at Silvia's apartment again. She is a wonderful hostess and a very kind person, the apartment is convenient and comfortable, the location is special, and the city of Valencia, is a great place to visit.
