I was in London for three days and Esther’s house is perfect for that. The room is extremely clean, looks exactly like in the pictures and you can reach the centre of London pretty fast with the near/very near public transportations.
Also, I enjoyed staying there for those days not only for the comfort of the house/room but also for the hospitality and the kindness of Esther and her family.
For all these reasons, I can totally recommend you staying there for your trip in London!
Thanks for everything Esther, cheers!
