Wow! What a location. If you're going to visit Valencia, this is where you want to be. Very neat and tidy apartment.
But here's some additional info: it's small but 4 persons are ok. It's on the third floor which in Spain means the 4th floor and yes, there's an elevator. But the elevator doesn't start on the ground floor, it starts on the first. So if you have issues with stairs or can't carry your suitcases up one flight, well, you may want to reconsider. There's a clothes washer but no dryer. The apartment has a convenient place to hang your clothes to dry and we had no problem with "eco-friendly" drying of our clothes.
Inma is an amazing host and will not rest until she knows you are happy. We stayed mid June 2022 for 3 nights, two couples plus an infant. Great visit.
Suggestion: walk the 20 meters to the Central Market each morning and get your fresh breakfast goodies there.
