The apartment is nice, clean and pretty well connected, being very close both to Earl's Court underground station and to various bus stops. The neighbourhood is quiet and you can relax after a hectic day. Alexandre was very accommodating and he let us check out quite late.
The only thing we didn't appreciate was the sofa bed. I spent two nights on it and woke up on both occasions with a very sore back. The bed was comfortable though.
So, apart from the sofa bed, we enjoyed our stay and would recommend it.
