Brett's place is hosted by his mum - who is a delight. The facilities are compact, but spotlessly clean, really close to local buses, trains, and the tram. The tram and bus both go to and from Edinburgh airport - not sure about the train as I didn't use it. If you like walking and the weather is fine, you can stroll into the heart of the city in no more than 30 minutes, maybe less.
Take my tip and ask Brett's mum to cook your evening meal. The additional cost is well worth it. It's Thai style cuisine, and the Pad Thai is to die for - best I've had!!!
All in all, an extremely pleasant stay.
