Location of this unit can't be beat, as it is in close proximity to all the best that Edinburgh has to offer. Make sure though, that you are up for lugging your suitcases up 3 flights of stairs, possibly in the dark. The key system (there were, I believe, 5 different locks, 2 needing skeleton keys) leaves much to be desired. You definitely want to have your wits about you when coming or going. Jeremy's "team" was very responsive with their communication and the directions to finding the keys were very clear, although I'm not sure if they are aware of the fact that there are now 2 lock boxes attached to the railing ~ we had to guess which one was the correct one. It felt rather like a scavenger hunt.
