The flat was absolutely perfect for our stay in Edinburgh - recently renovated, super clean, and stocked with everything we needed. It's in a beautiful neighborhood and there's a great coffee shop downstairs where we enjoyed breakfast. We walked everywhere during our stay, as we were just on the doorstep of all the fringe action and sites. There isn't a lift on the way up, so worth noting in case you have difficulty with stairs.
A bit about the host - Colin was super nice and helpful! He made sure we had everything we needed and made us feel at home.
