Flat is right at the foot of the Grassmarket. Ideal location- close to the Old Town center but don't have to deal with foot traffic. Make sure you get a description from Ann of what the place looks like from the street/what businesses are near by. Map applications would take us to the wrong location. Place feels very homey and Ann added touches here and there to reflect the city. Bottle of wine as a welcome was an awesome touch. Ann had heater on for us when we arrived and welcomed us to use it. Leaves clear instructions on how to work all heaters, wifi, etc. Gorgeous view of the castle when you step outside.
