Lovely little hotel ! Perfect location, just around the corner to Notting Hill (max 5 min to Bayswater tube st). Large and nice public areas, pleasant reception with competent and polite staff. I had a single room, so it was tiny, of course, but well positioned. It was perfectly sufficient for one night stay. Bathroom was too tiny though (you need to be UK-size 8).
Everything's spotlessly clean !
I'd definitely recommand and would love to return to the London House Hotel.
