Lynne's apartment is located at a fantastic location and being a corner apartment indeed has a beautiful castle view from every window!
The shower is large and really good and everything was clean and smelled great when we entered.
Lynne is a superb host, she greeted us upon check-in (and mind you, we checked in rather late) and gave us a lot of excellent tips and things to do in the few days we had in Edinburgh.
Highly recommended.
