If you are spending time in Edinburg we would recomment to book Tatu's place (if its free of course ;)). Location of the house is near main road to the center but enough away that you could sleep normaly and its just a max 3 min walk to the bus station where bus takes you to the center (15-30min drive, depends on a traffic). Appartment was very clean and confortable. The only thing that maybe we were missing was a small fridge for some drink.
