We had a good experience at Keith's place. The flat is 25-30 mins walking and 10 mins by bus to the city center. The Lothian buses are 2 mins away. Arthur's Seat is very accesible from his location. The flat is nice, spacious, although the room with the single bed is quite small. It was a little bit too cold, but overally it was a good experience. Sainsbury's is very close to this location and it is important if you want to do groceries and to cook, because eating outside could be expensive.
