Upon arriving, I discovered that I was two days early for our booked stay. Somehow I got into the building and accidentally left a suitcase inside. I called the phone number, reached Phillip, who helps manage the apartment. He came by within five minutes and helped me out.
The apartment has very comfortable beds and a great shower. I was happy to find a grocery store at the end of the block, also a couple of bakeries, and some take away food restaurants. Just a couple minutes walk, and we were able to catch a bus that took us to Holyrood Palace and up the Royal Mile quite a distance. About a fifteen minutes walk puts you at the main trail for Arthur's Seat. Super convenient.
