We had a great time at Sarah Jane's.
The appartment is beautiful, full with personality and spirit. You can see the owners' (Sarah and Steve) pictures everywhere, there are books, furniture. It's a real HOME (rather than AirBnB brochure life-less apartments).
It's equipped with all necessary facilities - great and convenient (yet very compact) kitchen with all the appliances. Amazing garden to have breakfast at.
Two great bedroom.
One of the things we really appreciated was the fact that we could sleep with windows open - it's so quiet!
Sarah was very communicative and helpful!
The only downside of this place is the distance from London center, it's in Zone3, so take this into account in terms of commute prices etc.
