This place is absolutely fantastic! It is right in the middle of everything within the center of Edinburgh so it is a perfect spot for the castle (which you have a beautiful view of directly from the place), Royal Mile, shopping, and eating. It is definitely a small space, so don't try and squeeze in more people here but for one or two people it is a cozy little place in the midst of it all.
As a host Olive was exceptionally on top of things. She made sure I knew about things I didn't even think to question yet and was attentive my entire stay!
