Absolutely brilliant hosts. Wonderful house and in a nice part of the city -- the buses are frequent and quick and can drop you off in the middle of the Royal Mile. Whilst there are (apparently) usually dogs in the house the two that were there when I stayed were some of the most incredibly well trained dogs I've ever seen (both current or retired guide dogs). Accommodation is up on the second floor, large room with comfortable bed and your own shower (only shared with someone else if there's another person staying in the house).
