We had a lovely time staying in Mark's guest room. It's spacious, bright even on cloudy days, and has a wonderful view. The bed is very comfortable with a luxurious duvet. The location on the Royal Mile is perfect, close to everything—the train station, museums, etc.—and being able to use the kitchen is a real plus. Our daughter was amused when we referred to the flat as "home," but it really felt that way.
