Uwe is a great host. He was very welcoming when we arrived, even though it was quite late (past 9pm). His apartment was clean and had everything you need for a comfortable stay. The flat was perfect for my group of 5 peoples. In terms of location, its close to pretty much every places, we can walk to the city centre within 30mins. There is the famous Arthur's Seats nearby which you can consider visiting for a great hiking.
Definitely will stay here again when we return to Edinburgh. I highly recommend this to anyone who is planning on short visit to Edinburgh.
