This is a really cool property and perfect if you want to be in a convenient location. It's very close to nice restaurants, bars, and historical sites. The biggest bonus for me is that the central market is right down the street.
I was a bit skeptical after reading a few reviews about it not being stocked with essentials but I didn't find this to be the case. We had more than enough of everything we needed including paper towels, shower supplies, TP, and kitchenware. The only thing I will say is be prepared for a bit of a hike up to the third floor through a narrow staircase. It wasn't a problem for us aside from lugging our luggage up, but I could see it being a problem if you have mobility issues. I personally prefer being off the ground floor, but I thought I'd mention it so you know what you're getting into. Overall, I would highly recommend this rental and plan on staying there again if/when I make my way back to beautiful Valencia.
