Olivier's flat is better than described on the post. It is well-located, close to a nice park (that my son loved) and a walk distance to the train, that takes you in minutes to the heart of London. The flat itself is well-maintaned with good furniture and an amazing shower (which is rare in London). On top of it, Olivier and his wife are amazing hosts -- they helped us in everything that we needed and even welcomed us with chocolates and wine. We really appreciated spending some weeks at their place. And would come again.
