The location of Dani's place is really great. 10 mins from Nord train station, a short walk to Mercado Central, and generally a safe area.
Communication with Dani was prompt and thorough. He provided a detailed walk-through on check-in and replied to questions via text quickly.
The space is great for a solo traveler, a private room with shared bathrooms in an apartment. That being said, the walls are quite thin and you tend to hear everything else going on in the apartment. It didn't bother me, but it's something to aware of. The apartment is also cleaned often (daily, I believe) so it is a clean environment.
I had the opportunity to meet some of the other guests and they were all really cool. The experience was sort of like a nice hostel but with your own private room. I would definitely stay here again next time I'm in Valencia.
