The apartment on Dr Zamenhof was perfect for us! It was a close walk to my internship and the old town. It’s a short cab ride to the city center and a 15 min to the beaches. Fernando was so friendly and helpful with a lot of local recommendations. Be prepared not to have a clothes dryer (just a washer), but there is a laundromat just down the street if you need to dry things. Lots of great cafes, restaurants and shops nearby.
Valencia is known to have occasional odor problems with sewer issues and that flared up from time to time but wasn’t unbearable.
