I had a great experience with Angie. The entire house is very clean and quiet. The room is big, with a big and very comfortable bed. WiFi works very fine. You don't need to worry about drinking water, because Angie have a filter which you can use.
From the airport you need to take 2 buses to go to the house, but if you want to go to the city center is easier, just take one bus in a lot of stops near there.
There's a pub in the street (Doo'cot) with nice food and beer prices, and a open-sky shopping near there, with a supermarket and drugstore. Angie is very kind and she helps you giving directions.
Edinburgh is an awesome city, with a lot of things to do. Don't forget to climb the Arthur's Seat, where you can see the entire region. Edinburgh Castle is great inside, it’s worth it! National Gallery and Scottish Museum are free, and a must go. And if you love beer (the real one's) you must know BrewDog, at the city center.
Very nice stay. I recommend Angie's house.
