Carlos gets wonderful reviews as a host, and this flat also gets wonderful reviews - and having spent a week there I can personally confirm that these reviews are 100% accurate. This has been my best Airbnb experience by a mile.
Although we didn't meet in person, Carlos was the perfect host and and nothing was too much trouble. He is very proactive, and that leaves you to just enjoy Valencia! The flat itself is spotless, has everything you need, and is in a really outstanding location.
I would have no hesitation in recommending this flat, and would be delighted to stay here again the next time I'm in Valencia.
