We had a wonderful stay at Caroline's apt. The location is perfect. We were about a 5-10 minute walk to the airport tram and the main bus terminal and no more than a 15 minute walk from the Waverly train station. Caroline provided us with detailed instructions for how to get to her place and the self-check-in process was very easy The apt. is in a quiet neighborhood and is fully equipped with everything you need. Like reviewers have mentioned it is a second floor walkup but we had no problems. The location is close to shopping, restaurants and museums. I would highly recommend this accommodation and would definitely stay here again if I come back to Edinburgh.
