Greg was quick to respond to any of our questions. He was good enough to let us put our bags in the unit earlier than the check in time so we could explore the city. Unit clean and updated. It is a small unit and stairs are narrow, but you only have to walk up one flight. Lock boxes easy to use and once we understand which keys to use for outside door and unit all was fine. Skeleton keys for unit was a new for us. Location was great! Quick walk to Grassmarket, Victoria Street and Royal Mile. Scotch Museum right across the street! Loved looking out at Greyfriar's Kirkyard from the unit. Some reviews mentioned that it was a noisy location, but we found it relatively quiet for being a city location. Earplugs included but not used. Enjoyed our stay very much.
