Yvonne is maybe one of the nicest hosts I've ever met through AirBNB (which is really hard because all of them were lovely!). Her house is very beautifully furnished, the room is quite big and the private bathroom is supplied with everything one needs (towels, hand soap, lotion, shower gel, etc.).
The flat is located in a quiet area which was very much to my liking as I slept really well and without noise - however there are a lot of busses connecting to the city centre within about 5 to 10 minutes; the house is easy to find and close to Portobello which is also a beautiful place to visit when being in Edinburgh. All in all, I can only recommend Yvonne's place!
