We booked that accommodation expecting nothing much because it was rather cheap.
it is greatly located (half an hour to central London), the room and bathrooms were very clean upon arrival.
Jean was very reactive and helpful.
The area is very safe as well.
Of course your stay is influenced by who else is staying there, depending on their ability to not be too loud and keep things clean, but this has nothing to do with the accommodation itself.
I would definitely stay there again.
