Maite was responsive and helped me feel at home. My Spanish is next to non-existent, and her English is not strong. Nevertheless, we managed to communicate effectively. She drew a map of the area for me. That was helpful.
The apartment in or immediately adjacent to the old city, a short walk from the Mercado Central and from the train station. The street that the apartment is on and the inside of the building are a little dark, but perfectly safe and comfortable.
The air conditioner in the apartment works well, and that is important in Valencia, even in late October.
