The apartment is beautifully decorated and matches the photos. It is set in an amazing location and all the major sites are easily walkable.
We were met on arrival by Pedrololo who gave us lots of excellent recommendations and was very friendly.
We loved how accommodating he was - he gave us a comfy mattress for the sofa bed and provided us with shampoo and towels.
Things to note: the apartment is only accessible by four flights of stairs, and due to its location it can be quite noisy at night and in the early morning. We also had a slight issue with the plumbing in that the toilet cistern didn't fill up regularly.
However I would recommend this as a place to stay if you want to explore this stunning city!
