The flat is SO central, literally 5-10 minutes walk to main tourist attractions and streets.
The flat itself looks bigger than in the pictures, which was a great surprise to us. It was really, really clean and had everything we needed for our stay. It had a beautiful decoration as well and we made a good use of the fireplace!
Also, there are a few boarding games which we played and had a lot of fun.
There were maps available and more touristy info which we appreciated.
Derek is a good host and would totally recommend to stay in this flat. If we had to come back to Edinburgh, we would definitely return to Derek's accommodation!
