This is an absolutely beautiful and special place in an incredible historic building!
First, important considerations:
excellent location- really well-situated on the Royal Mile, easy to get everywhere. there is a great pub in the courtyard/Close behind Gladstone's Yard (but people go inside after 10pm so outside noise wasnt really an issue)
very clean- everything was pristine!
bed- COMFY! (this is a thing I wish reviewers regularly mentioned!) this apartment had the most cozy, wonderful Queen size bed!
bathroom and kitchen- good towels and great dishes and kitchenware. the bathroom is outfitted with shampoo/conditioner/shower gel.
be aware that there is very little in the kitchen to augment cooking efforts (no stocked cupboard of spices, oils, etc). just something to plan for, in light of the other main consideration for this apartment...
which is the daunting stairs.
The stairs are REAL- narrow, spiral, steep, 5 flights.
For me it was completely worth it and part of the incredible uniqueness of the historical building, but definitely be prepared to huff and puff with your suitcases if you, like me, are not in peak physical condition.
communication with the host, entry and check-out, were all super easy and prompt.
Would highly recommend!
