The flat is full of light during the day, the bed is big and comfortable and everything was super clean and we had no problems inside the flat. On the morning though, it was very noisy, we could hear the neighbours activity and the water running down the pipes. I guess its just the way the walls have been build.
Otherwise the flat is also very near to the metro station Patraix, so you have a good access to the other places in Valencia.
We were very nicely received by Ivan, he will give you useful tips, like to take the bus 99 to go to the oceanografic and elsewhere. Plus he has written indications on airbnb for these kind of things (but I didn't take time to read this).
It was the flat I needed : affordable and near the metro.
