Mark is a very nice host, he provided a lot of information in Edinburgh, we had a brief talk after I arrived. I stayed at his department for 2 nights, and then I attended the Rabbie's tour, Mark still provided me a lot of help when I was in Isle of Skye. Also the department is located at Canongate which next to Royal Mile, you can go everywhere in old town easily. Furthermore, I discovered an unique store called "Canongate Jerseys and Crafts ltd" just next to Mark's department, which sells products full of Gaelic style, and lots of beautiful handmade knitwear. Recommend you must visit it if you would like to buy some good products in Edinburgh.
