I thoroughly enjoyed my stay at Iain's. The apartment is in a great area, right next to public transport and supermarkets. Cafés, restaurants, and pubs are also only a couple of minutes' walk away and Iain is happy to offer recommendations (which I always found to be amazing).
The room itself is very nice with a very comfortable bed and enough storage space, especially if you're staying for longer. Iain was the perfect host and great to chat to. His recommendations (be it restaurants, recipes, books, or events; inside and outside of Edinburgh) were always great and meant that I could experience things outside of the typical tourist attractions. I'll definitely try to come back the next time I'm in Edinburgh!
