Sarah was lovely and very welcoming: the room was for my parents coming to London for a couple of days. She let me take a look at the flat before booking it and the pictures show the flat as it truly is. Just one thing I think should be said: the room Sarah rents is her own, she, of course, stays somewhere else when occupied, but, even if it's quite large, there is no store space for guest. Still nice and cosy for short stays.
The neighborhood is very quite but full of shops, restaurants and supermarkets and well connected to the city centre. Ideal for my parents because they were staying just on the other side of the road from me.
