Our host, Caroline, contacted me very soon after my inquiry and we could quickly agree on the dates we were looking for so the booking was pretty straightforward. The flat is listed accurately. The location was super! Right in the middle of many Fringe Festival venues. Although there were lines outside the door for Festival events, into the evening, it didn't disturb us at all. We heard from locals that outside the festival dates, it is very calm and quiet, but we went for the excitement of the festival.
The actual apartment is quite spacious and clean. We felt spoiled with two bathrooms, both with showers (one had a shower and bathtub combination.) Since this was our first time visiting Edinburgh, we were very pleased with this accommodation.
