We spent 3 nights at Katie's place during our recent trip to Edinburgh. The accommodation is located about a 25 minute walk out of the city however there are plenty of buses running past the cottage. The cottage is lovely and spacious and quiet since it is detached and set back from the busy main road.
There were lots of additional extras provided by the host which were appreciated.
We had a lovely stay there, the only downsides were the sofa bed and main bed weren't very comfortable and the cottage can be quite noisy during high winds as we discovered during storm otto. Obviously the wind is out of the host's control.
