Having lived in Edinburgh previously for 4 years, the flat is in a great, central location. Very typical Edinburgh tenement building/stairwell. It is on the 4th floor - so quite a few stairs - BUT I was 7 months pregnant when I visited and didn't have any problems. They are nice wide stairs and absolutely fine if you just take it slow!
The room is very spacious and everything was really clean. Bed was super comfy too! The flat is really pretty and a lovely place to stay overall - would definitely recommend!
