Christian's place is newly renovated in a very clean and modern style, with everything one might need for a comfortable stay in the centre of Valencia. We were two couples with a dog. It was good having the two bathrooms, the beds are comfortable and flexible (two singles converting to double beds). The excellent kitchen is well equipped and the block is very quiet, despite being so close to the centre (a few minutes' walk from the central market).
Christian was in close contact and met us on arrival to let us in and show us around. The welcoming touches were very much appreciated.
Some of the streets nearby have a bit of a seedy feel, but not unsafe. It is a great spot in general though.
