Enjoyed a lovely stay at Sarah's flat in Quartermile. Was staying with my wife and 16 month old daughter. The location was nice and quiet, and I appreciated that the apartment had a lift -- which made getting the stroller in and out of the apartment very easy. Sarah went an extra step and got us a cot/crib for our daughter to sleep in and she slept well in it the entire stay. The full kitchen was nice, as we are often preparing meals and snacks for the little one and washing bottles and cups.
I will also mention the location of the apartment was perfect for a stay in Edinburgh. Close to city centre and the main tourist attractions in Edinburgh, but also near the University of Edinburgh, and a great city park, the Meadows. We enjoyed the park to the fullest and had a picnic there more than once and there are a few playgrounds as well. A lot of great restaurants and coffee shops nearby and a decent small grocery store as well.
Would love to stay again!
