About a 30 minute walk from the city centre or there are bus stops just a 5 minute walk from Pollock Halls. Basic, but very clean & the staff are friendly.
My only slight issue was the closing of the luggage storage. The reception is 24hr, however, you must pick your luggage up before 11pm. I was in Edinburgh for the Fringe, so dropped my suitcase off before the 3pm check-in & planned to check-in & pick up my suitcase around 1am after my last show. Whilst checking in at 1am is fine as there is always someone on reception, I wouldn't have got my suitcase. If the reception is 24/7 & the luggage storage area is just a cupboard off the reception area, why the 11pm cut off?
