Great stay in Joanna's flat, the appartment was very clean, confortable and welcoming ! Joanna has been very helpfull, and very fast to answer for each question we ask. This is a very good place to spend a few days in London.
Funny thing: The appartment is just 20 meters far from the Hugh Grant's house in "Notting Hill", in the SAME street (we discover it the last day by chance cos people take pictures of a mysterious blue door, we didn't know why at first...)
In short: best place to discover notting hill's atmosphere !
(and goods restaurants all around !)
