If you are visiting Edinburgh, I very highly recommend Conor's place. It's an entire apartment and can easily host 4 adults. The apartment is in the heart of the city and hence access to the entire city is very easy.
The apartment is a 200 year old one, as the description says, and it's the perfect blend of the old and the new. The apartment is very tastefully done and is squeaky clean. It looks exactly as in the pictures. I was pleasantly surprised at how well stocked the pantry was, especially the spice rack.
Also a word about Conor's hospitality. I had to disturb him at 10:30PM on a Sunday night and he was very accommodating to our query despite the odd hours. And the instructions to locate the house - well, in several years of staying in Airbnb across the world, I've never seen such clear, step-wise instructions ever! I am sure that he is well on his way to be a superhost.
Thank you, Conor for making our stay very comfortable. We were visiting with elderly parents and they truly felt at home there. The house is as pretty as the city of Edinburgh is and we will definitely be returning.
