Upon booking Ian kindly called up to inform me that his wife, who usually manges the BnB had been called away abroad for a family matter.
Due to this, he would be able to fulfill the booking with constraints on arrival times and breakfast times, and gave me the option to cancel.
I really appreciated the immediate contact and offer, but since the restrictions fitted my requirements anyway I went ahead with the booking.
Ian is a very friendly and personable host, who went out of his way to help me with directions during my time in Harrow and the London area.
The breakfast was excellent, cannot speak more highly of it.
