The apartment was well equipped and in a fabulous location off the Royal Mile and within walking distance to many sites. One perk was the amazing view of Arthur's Seat which I had the luxury of waking up to every morning. It was clean and had a great lay-out. Unfortunately, there are no lifts which made climbing up and down a few flights of stairs a bit strenuous, especially as we were a group of girls but may not be an issue for some. We had plumbing issues on the first day which became progressively worse as the days passed (culminating in a leak that affected the neighbours in the floors below causing us to be unable to use the kitchen sink and dishwasher) but the host seemed responsive in getting it sorted after our departure. I hope it was sorted before the new guests arrived. Seemed serious. I think a bolt or additional lock on the front door might be helpful for security reasons (we had a strange drunk man come knocking on the door one night and would have appreciated that extra layer of security). Apart from this, I would definitely recommend a stay at Colin's in the future for the reasons mentioned earlier.
