We loved staying at Sergio's place!
It was very centrally located, and a 2 minute walk from each of two Valenbisi locations, which we used every day to get around the city, to the beach etc. We could cycle on the Turia to get to the wonderful Museum of Fine Arts and to the Old town area with many great sightseeing spots. Valencia is a wonderful city!
We were also close to the shops, and a great vegan supermarket a few blocks away. We cooked a lot in the apartment with the two "burners" and enough pots and pans, cooking utensils etc. We could build good meals with the fresh vegetables and bread that were available from those shops just across the street.
The apartment was super quiet with the windows closed and the shutters drawn down. If it ever got too hot then we were able to use the air-conditioner. It was never that noisy with the windows and shutters open, either and the fresh air was felt throughout the apartment in that case.
All in all we really enjoyed Sergio's place in Valencia and recommend it to others!
