Easy to get to from centre of Edinburgh (lots of regular buses), Waverley station and the airport. Good communication from host and easy to check in (although the front door to the building takes a while to get the hang of). Shower pressure was great! Comfy bed and good heating system.
Only thing I would say is that I expected basics such as tea, coffee, oil and sugar to be provided, but there was only salt in the cupboard when we arrived. We ended up buying our own and leaving it in the flat.
