The location of Christians place is really nice for the inner city. We loved just popping over to the Central Market for lunch or groceries. We rented the city bikes to go around one day, and also took the bus to the beach one day. Lots of transportation options including Cabify.
The apartment needs a bit of sprucing up. Painting would be the main item. The neighbors all seem very friendly. The walls are a bit thin which is probably why keeping the noise level down is important.
We really like Valencia and I would recommend the apartment if you want to stay in this area.
