This hotel was the Inverness Court Hotel when I stayed there in September, 2000. It is a converted Victorian mansion in Bayswater, which we booked through the Holiday House brochure. IT IS NOT recommended! The lobby and stairwells were very elegant, the elevators small and slow. There were stairs once you got to your floor. Hmmm. The room was small as we expected, but our first impression was not great. The carpet was filthy, wallpaper yellowed, curtains hung limply. The outside glass doors to the balcony (well, just wide enough so you could stand if you wanted to brave the pigeon do-do) didn't shut and there was a hole in the glass about an inch round with cracks in the glass. We joked about our bullet hole! The inside sliding glass doors came off the runner once and would have every time if we weren't careful. The beds were narrow and really hard though at least the sheets were clean.
Checking on the hotel these days at Tripadvisor.com shows that it hasn't improved any and the customer service is really awful. I'd still say avoid at all costs.
convenient, across from Hyde park and around the corner from the Queensway underground station, a block from the Bayswater station.
