Here's the review of my colleague Stewart for whom I booked the room in John's house: "I have stayed here during the week on 3 separate occasions now and hopefully many more occasions to come. John's house is a home away from home for me while working in London. The property is accurately described, easy communications and john is very flexible with regards to my arrival time.
The room is quite large and the separate bathroom is a definite plus. Everything is spotlessly clean.
The location is convenient for Finsbury park underground and a short ride to central London."
