I Stayed here for 3 nights in January. The Apartment is very well located in the Old Town . 3 minute walk (if even) to the Cathedral and Placa De La Reina .
Everything you need is on the doorstep, supermarkets, bars/restaurants, sights.
The apartment was very clean, and well enough equipped for my short stay. (Some wine glasses would be nice:) )
I found the apartment to be a little chilly, but it was January, and Spanish apartments are designed to be cool in the summer months. In saying that, the heating worked well!
Emiliano was a pleasure to deal with, I arrived early in the morning, and he graciously allowed me to leave my bags in the apartment before check in. And also leave them for a few hours after check in as my flight was later in the day.
I would definitely return to this apartment, and recommend it to anyone travelling to Valencia.
¡Bon Viatge !
