Day 1, bedbug on the bed. Days 2-5 waking up to the smell of burnt toast from the breakfast room because the kitchen servants can't make toast properly. Extreme noise from traffic and people passing on Sussex Place at night.
Staff were almost all miserable and unhelpful. Breakfast is limited if you have dietary restrictions, just full cream milk with burnt toast and some other things. There was little attention to safety at the hotel, I nearly fell a badly hurt myself of a hidden step near the entrance. Lift only works for SOME of the upstairs rooms, beware.
If you are able to still cancel your reservation in time, I suggest you do it. Quite often room prices will go down close to arrival also, so don't worry. There are better hotels in the area, that are cheaper.
