We spent a lovely 2 nights at John's place during a road trip holiday this autumn. The location is brilliant, looking directly out onto the waterfront and around the corner from the beach and Cramond Island.
The pub 2 minutes away serves a great selection of ales and has a lovely atmosphere though unfortunately the food wasn't great (or we didn't pick well - we both had pies).
For our 2nd night we cooked in and the kitchen was perfectly equipped for a cosy meal in. There isn't a shop within walking distance but they're not far by bus or car, and John very generously stocked up on milk, juice, tea, coffee and snacks.
We enjoyed hopping on the bus into Edinburgh, rather than driving in, and enjoyed some exploring. Such a beautiful and interesting, and friendly, city.
I would definitely recommend this property as a cost bolt hole to explore Edinburgh from. If you are tall this grade b listed cottage has low-ceilings.
