A friend and I stayed at Pepa's flat for 5 nights. It was great. It's a very stylish and comfortable flat, very clean and well equipped.
It's in a great location in the old town very close to Mercado Central. We easily walked to lots of places and only got the metro a couple of times.
There is one bedroom and a sofa bed. I slept on the sofa and it was comfy and there was bedding available for it. The flat has shutters and air con and stayed nice and cool.
Pepa and her son were both very helpful - providing a guide to Valencia before we arrived and helping book.us an early morning taxi when we left.
I def recommend this air bnb and would stay there again.
