We stayed as a couple but the apartment accommodates more than 2 people as there are 2 bedrooms. There's a shower room and a bathroom too. It had everything we required for our 4 night stay and was clean and quiet. It is a bit out of the centre of Edinburgh, but it is easy to get into town by bus, taxi, or on foot for those who like a walk. Nearby are plenty cafes, restaurants and takeaways.
Barry and Steve are great communicators and are quick to respond if you have any queries. As well as written instructions on accessing the property, they provided a short video which was very helpful.
We would have no hesitation in recommending this Airbnb and its owners. It is definitely on our list for future visits to Edinburgh. Thanks to both of you.
