Firstly, the room is just off the Royal Mile (the primary happening road of the Edinburgh). You can just walk around the old town from here. All major pubs, tourist attractions, shops are nearby. I was able to walk to Edinburgh station from the room.
The flat is recently renovated so you will have new furnishing and bathroom fittings and well equipped kitchen. The flat has 2 rooms. William stays in other property so you have complete privacy during your stay. The only problem I faced was with room heating; I had to ping William to turn on the heating.
William is great host. He informed everything well beforehand and he was reachable during the stay. He also gave lots of toiletries, sleep masks, bathroom slippers etc.
I highly recommend this airbnb.
