We had a lovely stay at Rebecca’s apartment. We were right in the middle of the Royal Mile near many of the places we planned to visit. The apartment was clean and bright. Really liked the sunlights in the kitchen. The kitchen was well-appointed, too.
As others have mentioned, construction and/or late night pub patrons can be loud at times but we expected some level of that. Our only real challenge with this apartment was the stairs combined with how much we (over-)packed. Not a dealbreaker and the stairs were properly disclosed in the listing so we had only ourselves to blame. :)
If your plans bring you to Edinburgh and The Royal Mile, I would highly recommend a stay at this wonderful home!
