Mark and Doug have a lovely home and the room and bathroom were very clean and comfortable. We are a bit more private and it was our first time staying actually in someone's home, so we didn't socialize with them too much or use the common spaces. Both of us are fairly familiar with Edinburgh and were only staying for the night. It seemed that they were very open to chatting and all that though, so I imagine if you were on your own or new to the city they would offer a very nice experience.
