Andreu's place is truly a great airbnb. First of all, the location could not possibly be better. It's so well located and so easy to find, I didn't ever use google maps for my entire stay in Valencia. The room is great, with a nice, small balcony - or you can eat on the rooftop terrace. The kitchen is well-equipped and you're free to use their spices, etc. Andreu and his father are very nice and very helpful. We got a lot of tips about where to eat from Andreu and they were all amazing.
You can expect noise late at night but you're in the town centre and in Spain where life goes on into the night, so you can't count this against the property.
100% I would stay here next time I am in Valencia.
