The Pillar Hotel is by far the best kosher hotel in Northwest London. Located along several bus routes, traveling around is very easy. The Hendon Underground stop is a close ten minute walk.
The hotel offers a kosher breakfast. This is not included when booking through Expedia. Breakfast is 20 pounds PP daily. Better to walk up the street one of the local kosher eateries.
The hotel offers no other meals, not even Shabbat. They will set up a fridge for you as well as a hotplate and place settings, but you must provide your own food.
Parking is plentiful, the property quiet and idyllic and the staff very helpful and friendly. An excellent stay overall.
