Very nice place, stayed for New Year's which was an awesome experience doing the Street Party. Incredibly good value as we had another apartment booked with 4 other friends.
There apartment was considerably more expensive than Graham's, there beds weren't as comfy, it was smaller and on the 5th floor (stairs only).
Nice location to go up to Arthur's Seat and into the city centre.
Would also recommend Verdo for a fantastic meal out.
