We had flat 1 (3 bedroom/2 bath) apartment, which was super in terms of size, value and comfort. The kitchen was well equipped and the beds were very comfortable. The location is great for access to the University and Arthur's Seat, with many varied restaurants and pubs nearby.
I would just note that this property (as a whole) is not very stroller or wheelchair friendly, since you have to go up a lot of stairs to then go further up or down more stairs to access each flat. Keep this in mind when booking if you have children, a lot of luggage, or mobility issues. The property could have been a bit cleaner, but overall we were pleased with our choice to stay here.
