If you're a solo traveller or couple visiting Edinburgh then I'd thoroughly reccomed Ann's place. It's super centrally located to explore the city and the views of the castle are an added bonus.
The studio was very clean with all the fundamental amenities very well covered.
Communication with Ann was speedy and entry instructions were clear.
I really can't fault the place at all and if I'm ever in Edinburgh again then I'll be back here for sure.
