Jane's place is a lovely house. The centre of London is easily accessible by bus and metro. We spent there 2 nights, Jane was very kind and helpful, giving us precious local tips. The bedroom was very cosy and the bed comfortable and the shared bathroom was very clean. We felt welcomed at home and could also easily take some breakfast and a cup of tea in the common area of the house.
I definitely recommend that place and I hope to come back there in the future, while staying in London again.
