8 adults stayed at the flat during the Edinburgh festival. There was more than enough space for all of us with a large lounge area. The flat is well equipped and the beds are extremely comfortable. We did have an issue with the shower in the main bathroom (switching from hot to tepid with low pressure) however Jason was calling in an engineer to sort this out so hopefully it should no longer be a problem.
The location of the flat for the festival is great. The majority of venues are within walking distance and being on this side of town it is easier to get reservations in restaurants nearby.
