Great simple place to stay, can drive and park easily here, whereas city centre would be a nightmare to drive in. Taxi's in to the city centre (old town) 15mins and between £15-£20 each way - use central taxi's they were fantastic.
Bistro next door does great food, and a great old pub that does food and ales just behind the flat.
The flat has enough to keep you comfy, tv, good 3G coverage.
Cramond island is just outside the front door - it's a one off experience.
This was better than staying in the city centre because we could choose to go into the city via taxi, or drive to outer parts of the city, or the Forth bridge, etc - for example we went indoor go karting to nearby place in New bridge one day due to the rain.
John's a great host and keeps in contact if needed.
