Michael is a really really nice person. He was very thoughtful about my stay.
The flat is cozy and authentically British one.
It is well-equipped (especially cooking tools).
Maybe the negative point about it is that walls are thin (sometimes I heard someone taking in the next house).
The closest midseize supermarket is Co-op, 10 mins walk away (near Archway Station).
On the whole, I liked the flat and had a great time there.
