We spent two weeks in Valencia staying in Olga's and Dmitriy's flat.
The flat is situated quite near to the centre, just a 15-20 minutes walk or 5 minutes bike ride. We also rented a car for my husband who flew to Alicante but finding a parking slot in the evening is a fastidious task. Better to leave the car and rent a bike or escooter. Valencia is a very bike and scooter friendly city.
The flat is very cosy and immaculately clean. The room facing the street was a bit noisy but it did not bother us much. We enjoyed our stay greatly and would warmly recommend Olga's and Dmitry's place.
