Isla is a great host who works hard to make sure you've everything you need, even rushing around the night before when I said we had an extra guest.
The house is typical Edinburgh architectural beauty, I love those old buildings and love to think how they used to be inhabited. It does lead to drawbacks though as the lay out isn't quite conducive to socialising ten people. The kitchen is on the top floor and not very big and the living room is the floor below, so any drinks must be made and carried down the splendid staircase so you can sit comfortably to enjoy it.
One shower in the house is one less than ideal but there is a bath and two can easily shower at a time to speed things up, and the shower is a powerful beast.
Plenty of keys are left so everyone can enjoy the city at their leisure and there is of course plenty about Edinburgh to be enjoyed.
I highly recommend this place if you've got a group of 6 as anymore starts to put a stress on dining and sleeping, unless you're really friendly :)
