The location of the apartment is very good, right in the center of Valencia. The building is well maintained. The apartment is spacious and well equipped, we could not say that we lacked something. The internet connection was very good.
The unpleasant part was related to the communication part, when they took the data from airbnb, entered it in their own communication system and started sending us emails to pay for the accommodation we paid for in airbnb, to make a deposit not mentioned in the process. booking ... they gave us the impression that it was a fake accommodation. Eventually these issues were clarified but traveling with a small child this confusion in communication was a bit stressful.
However, the cleaning service, which I saw was charged separately, left much to be desired. After cleaning, they left the dishes unwashed in the sink and the messenger garbage in the trash :)
