First and foremost: Ross is a wonderful host, even by Scottish standards.
The flat is perfectly located (we actually watched the Hogmanay torchlight procession through the living room windows), the bathroom is plentifully equipped, the couch and bed are super comfy and the neighbourhood was fairly quiet.
Being a city flat, a few areas are a bit on the tight side of things but other than that, everything was splendid.
Many thanks, Ross!
