We stayed one week in Vicente's appartment and had a great time! The location is amazing, right in the center of Valencia's old town, everything is walking distance, especially tons of cafes, restaurants and bars. Of course, since there is one bar with outside seating right underneath the three little balconies of the flat, it does get noisy, especially during the day, but that can be expected for booking a place in the center. With that said, the windows of the bedroom shut out noise and light surprisingly well and we actually slept great in the comfy bed. We did not cook, but for coffee/snacks, the kitchen was perfectly equipped.
Highly recommended for a city trip to Valencia!
