You know how a great wine pairing can transcend a dinner ? Well, Lily's appartement had that effect on my Edinburgh visit. It is absolutely fantastic, I just loved it. Located in the very heart of the old town, all major sites are close and you can do everything on foot. It is wonderfuly cozy, comfortable and offers all the amenities you need. Returning to the flat after a day of exploring the city was a real pleasure.
Note : Just be aware that the appt is on the 3rd floor and that there is no elevator. Personnaly I saw that as an advantage, as there were so many delicious restaurants in the neighborhood ; climbing a few stairs can't hurt :p
