Never met the host in person, but our communication was impeccable. The roomate living in the apartment was friendly, respectable and easy to get along with. Location in Old Town was excellent especially with the Fringe festival going on. I was able to walk to the Edinburgh castle and the Royal Mile quickly and easily. Rafal gave me many tips and suggestions on where to go and places to get coffee/eat also.
Keep in mind there is no elevator in the building.
