Our family all had a great time staying in Gardner's Crescent - it's a spacious apartment with high ceilings and good-sized bedrooms. The kitchen looked to be well equipped but we only ever ate breakfast there - including some very nice croissants kindly provided by Paul & Dorothy for our first morning, plus milk for our teas & coffees.
So easy to walk to the Fringe venues and into the centre of Edinburgh but in a quiet location - we slept very well at night in the comfortable beds.
We would definitely recommend Gardener's Crescent as a place to stay & indeed would happily do so when we next go to the Edinburgh Fringe Festival.
