We had a very nice time in Edinburgh! Lucy’s place is about a 20min walk from the centre and very easy get to from the airport. We only saw lucy shortly but she was very nice and we felt welcome. She also gave some good restaurant reccomendations! The bedroom is small and simple but if you are planning to be out all day, that is no problem. I think you are also allowed to use kitchen and living room, but we didn’t do this.
