I stayed at Carol's in an overnight stay in Edinburgh. Communication was great and although Carol was not around, her brother David let me in and was very hospitable. At his suggestion I left my car at the house, and caught the bus into the central town area, all of 10 mins away, where I enjoyed the afternoon and evening. The bus home was equally painless, and runs all night. It was about every 5 mins when I was catching it.
The room was nicely made up, and plenty of space. The bathroom was right next door, and made it feel almost ensuite!
One thing to be careful of, is that the front faces a busy road, and there is not a lot of room to pull a car in, or out. But other than the traffic, it was great!
I would gladly stay with carol again if I am in the area!
