I stayed for one month. Initially Zdenka and her family were there, so we had a couple of chats. They are lovely people. They have also been quite helpful and caring. They then moved out and the rest of my booked period passed with just other guests in the flat. I never had a problem.
The fact of having a well-size fridge in the room was a great commodity for my long stay, though I am extra-sensitive to noise, so I turned it off for the night (even the buzz of a transformer doesn't let me sleep). For a countryside person there is a little background noise from the traffic (well, like anywhere in London!), to which I am not used, but even someone as sensitive as me could sleep well, there. The other two rooms are actually totally quiet, as facing the lovely court garden.
Comparing with other accommodations in the area, I wish I had booked a longer period! It's in a good location, quite convenient for me, having to work in Hammersmith and very close to all sorts of markets, pubs, restaurant and a flourishing Saturday market (where I found even Montalbano's arancini!).
