Deborah's place was perfect for our trip to Edinburgh for the New Year. Located right at the end of the Royal Mile, we were able to walk into town every day. The place was nice and warm, and had everything we needed for our few day stay. The grocery store was a short walk away, and there were several bus stops situated nearby.
The only things to note are that the unit is adjacent to a fairly busy road, so the sound of cars can be loud at night, especially in the living room (ear plugs or white noise worked well for me). Additionally, the towels smelled a bit of cigarette smoke.
All things considered, we had a lovely stay!
