The good: the location (very convenient if you are arriving or departing from Paddington Station).
Our room was very clean and the bed was comfortable.
The daytime desk clerk was pleasant and efficient.
The mediocre: the included breakfast is okay but bland. Cold cereal, some sliced tomato and bread for toasting. No interesting roals, pastries, etc. And no hot food.
The bad: there is no elevator. There are very steep stairs that are difficult to negotiate, especially with suitcases.
The bathroom is tiny and the shower miniscule.
The night desk clerk was incredibly annoying. I requested our boarding passes for our flight the next day. She did do that, but with it came a patronizing lecture on how to get to the airport, when I should get there, etc., ignoring the fact that I have done this trip many times.
There seemed to be no insulation between our ceiling and the room above us; it was very noisy at night.
