Great communication with Lisa before our stay. We had to switch rooms for the last night and she made it very easy. Kayla was very cheerful even though we arrived an hour early unexpectedly, and she chatted with us several times through our stay but was never intrusive. The best thing I can say about this listing is the location! Calton Hill is perfect, with a 5-10 minute walk to the Royal Mile and no more than 20 minutes from most of the typical tourist things (plus Howies down the street was one of the best meals we had on our entire trip). The mattress on the superking was replaced the day we left, so I can't comment on that other than to say you'll have a nice new bed to sleep in. The bathroom was adequate. The washer was easier to use than others we encountered on our trip and she helpfully provided detergent. We were fortunate that the other people staying in the other room while we were there were all quiet and considerate. There is a simple latch to lock the door to your room if you are in it, but one minor wish for my paranoid side was the ability to lock the room when I was away from my stuff. The property is older, so the hallway coming up to the flat is a little dingy as you come in, but don't let it fool you as the flat is totally different. I would definitely stay here again and recommend it to anyone considering!
