I spent 4 nights at Callum's lovely flat. The room was great and his flat is lovely - spotlessly clean.
Callum is a lovely & friendly guy and made me feel totally at home. Breakfast was available with juice, yoghurts, toast an a good range of cereals.
The flat is conveniently located, about 20 mins walk from Waverley Station. All in all a perfect place to stay and I'd definitely stay again.
