Moira's apartment is great!
We were a group of 8 people staying over a weekend in December. The location is perfect: a quiet neighbourhood in the city center, not far away from the castle and just 15 minutes by walk from Prince's street (where there is the tram connection to the airport). The meadows are behind the corner so the opportunity to go running or walking through the park.
The house has plenty of space: 3 huge double rooms, and 2 single rooms. In case, the airbed can be inflated and fit in one of the double rooms (I told you they are huge), so to make space for extra people while keeping the living room free.
The kitchen is fully operational and the living room is cosy, with a long table where we could eat all together.
Everything is very clean and tidy. Noticeably, the bedsheets are of high quality and there are also plenty of towels. The apartment is warm and there is almost unlimited supply of hot water.
I think it has been one of my best experience with AirB&B.
Highly recommended especially if you are a large group.
Cheers and enjoy Edinburgh!
