Hannah is a great host. She was easy to get a hold of, quick to respond and very helpful and accommodating.
The flat itself is great, exactly as advertised, clean and in a spectacular location (the flat does back a rail line so you might hear the trains in the morning if you're a light sleeper). It has a great view of Arthur's Seat and it's only a very short stroll to Holyrood Park and the Royal Mile.
Hannah provided a bunch of helpful guide books and local area information, as well as some Scottish treats and emergency toiletries – which was especially helpful when I realised I'd forgotten to pack a few things in my mad dash out the door. Overall, my friend and I had a great experience, and I would definitely recommend staying at Hannah's for your next trip to Edinburgh.
