I was overall really happy to stay in this apartment, I agree the best description of the flat is indeed "cozy", it has all the amenities and it was as neat as a hotel. The host was a really kind guy and he was always aware of me having everything I needed. I even had a chance to interact with the neighbors which end up being quite helpful for my trip in Edinburgh. I guess there is still quite a 25 min walking distance from the city centre (or at least what I as a tourist considered the main hub), however it's just 4 min walk from the #8bus stop that takes you there. I would definitely come back to this flat.
