Me and my girlfriend stayed in the apartment for 4 weeks (mid July 2021 - mid August 2021). Apartment is very nice and had amazing location in El Carmen (the "old town" of Valencia).
It has everything needed for a long vacation. Can't mention everything it has, it is a long list.
It is at 2 min walk from the most crowded areas of El Carmen, so it was not super noisy. But still do not expect very quiet atmosphere in El Carmen.
Totally would recommend the apartment and Mia (the host). For sure for our next visit in Valencia we would use it again in case it is free.
