Renato is a really nice and caring host. I felt very welcome there and had a pleasant time. He can give you good tips where to go, where you can eat and go out.
The apartment is in a very central but for a large city calm area and even as it was very hot during the night, it was manageable to sleep. It is very clean and has everything you need.
So I highly recommend Renato and his apartment, if you want to go to Valencia!
