The flat is lovely, functional, and clean. The beds are full size and there's more than enough closet space. There's no elevator so be careful going up the stairs with your luggage. Carry on one suit case at a time if you have multiple pieces.
About 20 to 30-minute walk from the famous Royal Mile and about 10 minutes from the major rail station Waverley. Multiple restaurants are close by.
I wasn't able to take my smart phone with me and so our host Eddie was very gracious to agree to communicate with me via my wive's phone. Easy self check-in/out. Overall, a nice experience.
