Carlos and Orinda were lovely hosts! Communication with them is clear and direct, but still warm and friendly.
We sadly did not receive the mentioned email containing the info and recommendations of what to do in the neighborhood, etc. but it's not really a dealbreaker—we understand that sometimes people just have other more important things to do.
It also helps that the location of the apartment is great! A lot of local spots can be easily reached by foot. Locations that require a whole day to explore like the City of Arts and Sciences/Ciudad de las Artes y las Ciencias meanwhile, are one bus ride away. If you don't know your way around, G*ogle Maps is invaluable!
All in all, if we find ourselves planning another trip to Valencia, we would be thinking of this apartment first as an option for accommodation!
