As others have stated, the noise is the biggest issue here. I had anticipated that the proximity to the Royal Mile would mean people/crowd noise (and during festival season I am sure that is true), but it was actually traffic noise from a busy cross-street that was the most noticible. So bring earplugs! But if you are going to be out and about most of your stay and want a very conveniently located place to crash, this fits the bill. There were a few maintenance issues, but the team was quick to respond so I am sure that will be addressed. Check-in/check-out were seamless, and overall we enjoyed our stay.
