Stayed at Niki's place for a weekend with 2 friends. It was a great location, just across the road from the entrance to Holyrood park, you could walk through the park to the parliament and then further onto the royal mile. To the centre was prob a 25/30 min walk but to get to the area at the borrow of the royal mile was less and it was a lovely walk.
It was easy to contact the host and everything was ready for us, its a quiet area which is just what we wanted after spending the days in the city. Lovely balcony to relax on with a fantastic view or Arthurs seat (we were lucky with great weather!)
