Apartment was lovely and clean. Looks just like the pictures. The location couldn't be better. You walk out of the front door and you're looking at the castle. Close to restaurants, bars, coffee shops, shopping and a tesco if needed. We also walked to Arthur's seat which was about 30 minute walk (can't recall exactly) but was a nice walk. Close to main transportation lines as well if you don't want to walk.
The host was very friendly and even had tea/biscuits and a bottle of wine set out when we got there. She was very easy to contact as well. The apartment has everything you need.
It was a lovely stay in Edinburgh and I would most definitely recommend this location and host! A+.
