A very clean, unexpectedly spacious, one-bedroom flat with excellent transport links (the description is correct - VERY frequent buses into the centre) and a short walk away from the starting point/gardens at the base of Arthur's Seat.
The check-in process was a hands-free doddle; the flat is tranquil, spotless, minimalist and nicely decorated. We felt very relaxed there overall & were able to have a good night's sleep.
We came for the Fringe & getting in and out of town was super easy, with buses running overnight as well.
We would definitely come back here. The only drawback is the price once fees are included (so factor that in)... however, this is far more spacious & far cosier compared to a hotel room!
