Robert was an excellent host, easy to reach with questions even though we didn't overlap much. The flat is even lovelier and cozier than the pictures on AirBnB suggest--I was pleasantly surprised when I arrived. There's a great view of Arthur's Seat from the flat and the University area was very accessible, making it ideal for attending a conference. That said, the rest of the center city is within a half hour or so walk, so it's a pretty great location in general. I will definitely check Robert's listing first next time I'm planning a trip to Edinburgh.
