Can’t recommend this place enough. Came with my wife and two kids (4 and 2), and this was a perfect spot to experience old town. Minutes away from the core of the royal mile. The place was clean, quiet, and big enough to have space with the kids. Chris communicated within minutes if we had questions, and even provided a pack and play for the little one. Definitely watch the videos before check in, they’re a necessity.
We took the train in, but whether you come from train or tram, I’d recommend Ubering with all luggage rather than walking. Its not a far walk, but it’s tricky to find the place for the first time if you’ve never been to Edinburgh and you don’t want to deal with that and all the hills if you have a bunch of luggage.
