We spent four days at Andy's place. We can recommend it to someone who needs a place only to sleep in Edinburgh (because of good location) and do not need or want to cook at home.
If you look for a place to spend your holidays and know you will spend some time in the flat you might not find this place comfortable.
There were many things that did not match description. No self check-in, no breakfast provided, no dryer, no shampoo. Kitchen equipment was basic. You should consider taking or buying your own salt as there is none provided. Frying pans were quite used and scratched. The fridge was dirty inside.
