I love Valencia and especially the neighborhood. Although a lot of places in Rusafa seemed to be closed, I found a sweet spot Cafe ArtySana just a block away. Great to work from.
I stayed for two weeks. It was suuuuuuuper hot for a week of it but to be honest would have been hot anywhere. I don't think AC is really a thing in Europe.
Miguel was a super attentive and caring host. He took me to the doctor, he gave me watermelon and told me about the rooftop when I was going insane from the hear.
The room was small (and warm - just be prepared, its Valencia) but the bed was comfy, it was quiet and although there was only one bathroom it was rarely occupied.
I never cooked anything but the kitchen was available. There are restaurants galore in every direction and they're all great.
I would definitely recommend...just dont go in summer unless you can handle the heat ;)
