What a stunning apartment! I had a brief stay in Valencia this December and would've loved to have stayed longer.
Jose was very welcoming on arrival and gave a great run through of the apartment, instructions for staying and tips for things to do in the area. The apartment is very spacious and seems perfect for a couple or solo traveler who would want to spend some days relaxing or working in another city. As other guests have highlighted, it was a slight walk / commute on public transport to get to the main parts of the city. I opted to walk most places to get familiar with the area, the beach is a 5-10minute walk and was so nice to discover.
My only difficulty during the short stay was with the staircase going up to the bedroom. The steps are slightly narrow and slippy, which I did have difficulty with on the last day trying to bring my things down (I wasn't confident taking the suitcase up would be a good idea). I would also love to visit the city again in the spring or summer. Being winter the days were very windy and I could feel a slight draft coming through in the nights. The outdoor balcony at the apartment looks perfect for those warmer days.
On checking out I did have a slightly unexpected moment where I was stuck in between the apartment and building exit as the next door neighbour had locked the building entrance and I had left the keys inside the apartment! Jose was quick to assist and his sister came over to unlock the door for me.
All-in-all I would really recommend Jose's apartment if you're staying in Valencia.
