This apartment is in THE BEST location in Valencia. It's so central and in the old city, but it's on a quiet street, so it's not at all noisy. There's a staggering choice of cafes, bars and restaurants within 100m of the front door, and of course, many more eateries, shops and services in the rest of the old city. We hired bikes and really enjoyed our explorations of the city both on foot and using the bikes (plus there was a bike rack on the street corner, which was very convenient).
There's some lovely furnishings and old, exposed brick walls, which make the apartment stylish and unique.
There's also plenty of storage room, which was great as I find many AirBnB places offer limited storage. The apartment's on the 4th floor, which means 5 flights of steps from the foyer. Keep this in mind if you have heavy luggage or mobility issues. We had a few weird power outages on the first night when using the washing machine (we just flicked the power back using the main board), but everything was fine after that.
