Kaddeer was very clear in giving us directions to the flat. He wasn't there to meet us as we were late in arriving but had left our keys in a local shop and it was all very smooth sailing.
The flat is the PERFECT location if you want to experience the Fringe festival or any of Old Town Edinburgh. The kitchen overlooks the castle which is nice. Small things to work on would be the shower which can be temperamental and the blind which didn't work. Beds were super comfortable although be aware that if there is more than 2 of you, someone has to sleep on a camp bed. As our train was later than the check out time, Kaddeer let us put our bags in his family shop until we needed to go which was great and stopped us from having to lug our bags around.
