Mark gave us his mobile number early on, and contacted us a few times to make sure we knew where we were coming, he gave v good instructions for getting to him. He was flexible for us to leave our luggage before check in and after check out, so we could make the most of our time there.
It was a very good looking quiet and comfortable bedroom, very comfy beds, with "make your own" breakfasts, and plenty tea, coffee, milk etc. There was shared use of the bathroom with bath and good shower, nice living room and kitchen shared with Mark, but he was very unobtrusive and friendly and helpful when there.
We were there for the Edinburgh Festival Fringe and the flat is perfect for that.
