Highly recommend both the apartment and booking with John - he’s a great communicator and made the whole process smooth, informative, and pleasant. Check in and out was very easy with the key drop box. The apartment is in a super location near the castle and Grassmarket. It’s in the middle of the close (street) which makes it handy to access from either direction. It’s convenient to Old Town and the neighbourhood felt very safe to walk alone at night. The apartment is a walk up on the first floor and has everything you need. The clothes washing machine and drying rack came in very handy!Thanks again, John, for everything.
