My Mom and aunt stayed in Ali's place for four nights and were very happy with the convenient location, The place is clean and cozy and a very good value for money.
Ali is easy to communicate with and almost immediately replies to every email.
The check-in was smooth and, since they had a bus later in the afternoon, Ali graciously allowed them to leave the luggage in the office after the check-out.
I would recommend the apartment and be glad to stay there when visiting London.
