The best thing about this place is location, which is really great. You can walk from the apartment to every cool place in center Valencia.
We did not like the improvised bathroom with door that cannot be closed 100%. Also, maybe add some thing in the kitchen, like kitchen paper, bowls or coffee.
The first night the neighbors below us cooked fish and all the smell came through our kitchen because of the pipes, we had to keep the window open the whole night, so that was really bad.
