Sylvan's place is the most quaint and cozy Airbnb I have stayed at. She was a great help to me as one of my first nights in London she accepted a same day reservation from me.
The room is comfortable, really all that you could ask for. She was inviting and when I first arrived she offered me some tea.
Bus stations are less than a 5 minute walk away and from these stations you can get anywhere in London with relative ease.
Make note that there are two friendly cats that have a habit to come visit guests in the room. I enjoyed this but it is worth mentioning in case you leave the door open.
