We had a couple of nights at Chris and Sonia's as we wanted a bit of time in Edinburgh before leaving Scotland. The flat is in a great location, and benefits from being really central but on a quiet street. Chris and Sonia made us feel welcome ahead of time and they have also created an Insider's Guide App with suggestions for things to do, restaurants and the like. Despite having lived in Edinburgh before, the app was really useful. It was a great way to try new things and all the suggestions were top notch.
