Graham's place is very spacious, more so than the photos indicate, and very charming. We liked the neighborhood and were able to walk to all of the main sites. We like to walk, so even though the Botanical Garden was farther afield, we walked there too. The apartment was very clean. As for check in, Graham was right there when we arrived, very helpful as we were dropping off our luggage prior to returning our rental car to Waverly Station. I would note that just that brief amount of driving in Edinburgh was a nightmare and would not recommend it!
We would stay in this apartment again and would certainly recommend it.
