We travelled up from London and our break in Edinburgh was very relaxing. The flat is very clean, very comfortable, and nicely located away from the heavy tourist areas... but close enough to stroll over to them if you wish. The bed is firm, but we slept very well over the three nights. The flat is modern and comfortable, sparsely decorated, but with really nice choices (simple, but lovely?). I would highly recommend Ellie and Scott as hosts, for they were very prompt, friendly, and clear in all our communications.
Just a few tips for food and coffee: Mo Beans on Easter Rd is a block away, and the owner is super friendly! Good food and coffee (and an adorable rescue doggo is often there). The Red Kite cafe is about 3 blocks away, and we had some delicious breakfast and coffees there. Henderson's is around the back street from the Scottish Parliament, and they have a nice selection of organic vegetarian (and vegan) foods.
