I stayed with Toby for 7 weeks and he was a great host! The flat is very clean, modern kitchen, and spacious bedroom. I was there for research, and Toby was very considerate and will certainly give you space or converse with you however much you like! We were both in and out most of the time, but he was always very friendly and has a great knowledge of the city.
I would definitely recommend staying at his place, I certainly would if I return to Edinburgh!
