A nice and clean place to stay, right in the heart of Edinburgh. Provides a comfortable stay for four, six would be a bit of a stretch. You would be expected to do all of your own, form self check in to reading the instructions and learning how to deal with the heating. I do not understand while there is not a thermostat installed. The heating and hot water are very, good once you have learned how to turn them on/off directly from the boiler.
However, I will strongly recommend it. In addition, there is a convenient paid car park near by.
