The apartment was exactly as described. It's a nice room, and there's a basic bathroom (shared with the owner). Nusha is very friendly, but she doesn't speak English so it's sometimes difficult communicating with one another. She also smokes in the apartment, we didn't know this but it didn't bother us as much as we feared. Her little dog Kyra barked at us sometimes but was very friendly as well.
Overall it was a pleasant stay. The apartment is very well situated, exactly in between the old city center and the sea.
We really enjoyed our stay in Valencia!
