We liked the Gail's residence very much!
The flat isn't too big, but it's quite sufficient for 3-4 peolpe: two bedrooms (one small) and lounge with gas fireplace!!
Heartly hosts)
On the half way to the seaport and the center of Edinburg. It took us 30 minutes of walking to get to the crossing of the Royal mile and the North/South bridge. But there are also lots of buses near the residence.
It's easy to get there from the airport on the bus N300 (about an hour).
