I stayed in Danie's place while I was looking for long term accommodation and working. The location is just at the very heart of the old town, perfectly central. The flat was clean, bright and well ventilated. I shared the flat with Danie's son while Danie was away. He's a nice and private chap, so he made a perfect host!
The flat has a kitchen and a bathroom with bathtub and shower (shared). I stayed in the advertised double room while Danie's son was occupying the other room.
I really recommend Danie's place for a solo traveller or a couple if you're planning to visit Edinburgh!
