Hard to exaggerate how nice this place is; I felt like I was at home with my wife and 20month old boy. Really clean, beautiful decor, very big place, great facilities (washing machine and dryer, dishwasher, cooker), nice central heating for winter, private parking, easy lift access and much more. I drove to Queensferry to see the new bridge, Fort Kinnaird retail park, Ocean Terminal, Edinburgh Castle and the city centre; everything was extremely close! We got deliveries from a range of really good restaurants and used the kitchen to cook at the flat also. Great softplay centre for kids within a mile or so and it's right next to a big Tesco and around the corner from quite a few cafes, restaurants and shops.
If you need two rooms in Edinburgh then this is the place you need to stay in for sure.
