Great place!
Very secured place and easily accessable system of checking in and out with accommodating host and good reception staff. The check.in time is 15:00 but the host accommodated our request to leave our luggage in their reception before we check.in, so we can explore London without the burden of bringing our luggage with us around.
I am glad I found a slot for my travel, although we only stayed for 1night, we will definitely be booking for longer stay in the future.
