Sonia and Chris are great hosts and their apartment was amazing.
It is centrally located (only a 10 minute walk from Waverly Station) in Old Town. The apartment was lovely, with two spacious bedrooms and a very nice living room/kitchen area. The tv does have Netflix and they have a great record player with very good albums for you to listen to. They were so thoughtful and left very nice toiletries as well a nice welcome surprise!
Do yourself a favor and go through the very helpful booklet that Chris and Sonia leave on their kitchen table because you'll find some gems. We tried both The Devil's Advocate, which gave us the best meal in Edinburgh, and BrewDog were we had a great beer. Royal Mile itself is right behind their apartment and you can literally walk from Edinburgh castle to Holyrood Palace (the Queen's official Scotland residence).
