Overall we really enjoyed our stay in Valencia and the communication with our host was always great! The apartment is lovely and the pictures are very true to the apartment itself. Check in was very easy and hasslefree.
One thing to consider is the noisy location of the apartment if you are not staying out late. While it is a great location and very central for sightseeing during the day it can be tricky during the night if you want to sleep. There are a few restaurant close by which were open until Corona curfew started (1am) and it was always very loud until they were closed. Also the bed makes noises when you turn around which might be annoying to some people.
Overall though it was super convenient for our sightseeing trip and you have everything close by - restaurants, supermarket,... I would recommend the place if you stay for a few nights and are not super sensitive to noise.
