I very demanding person, but this apartment has satisfied me at all. It has all necessary facilities, it is nice, clean and comfortable. The location is good and calm, you can get to the center by feet in 20 minutes. Also very nice Paul and Illya who rent the apartment and in any question they will help you immediately. Guys have prepared clear tutorials how to find location, how to open the door etc. its easy and you will not have any problem with check-in or check-out.
It's my choice for future travels to Valencia.
