Marie's flat is lovely and in a great location. It has everything you need - kitchen supplies, comfy beds, nice towels. The second bed is a sofa bed, but is surprisingly comfy! We didn't realise that there isn't a tv (not essential & it's not listed in the amenities). There is a great music collection instead.
The train line is very close & can be a bit noisy, but we became used to it within a night or two.
There are 2 flights of stairs, so you have a great view of the London skyline.
Isabelle was lovely & very helpful while showing us the flat.
Hopefully we'll return when staying in London again.
