I've stayed here for 2 weeks here with my family (including a 2 year old kid) and it was all perfect.
The length Jose has gone to make us feel perfect is unbelievable.
He even prepared some toys for my son and left us 2 brand new boxes of coffee to use ;)
The apartment is brand new, freshly refurbished and it has all you need.
2 bedrooms face the street and it can be sometimes a little noisy there until 10-10:30pm.
After that it's quiet and we slept in several days without being disturbed by any noise.
The apartment has a nice little terrace that was great for a lazy coffee in the morning or a glass of wine under the stars.
Everything was great and Jose and his brother are very friendly.
I recommend checking his apartment next time you are in Valencia.
It is on my list and I'll try to book it next time I visit.
