We really enjoyed our stay at Vivien and Shaun's apt. The apt is very nicely finished and really cozy, everything is clean and well presented. The hosts were very pleasant and helped us when ever we required, and even though the apt in attached to their home, they were very unobtrusive and left us to our own business.
The location for us was perfect, we didn't drive once. It is about a 20 minute brisk walk into the city, but it's a great walk with lots to see and do on the way.
Overall we really enjoyed our stay, if I had to make any changes I would put a door on the bathroom for privacy, although that's just my personal preference. I would recommend this accomodation to anyone wanting a nice relaxing leisurely break to Edinburgh.
