The staff were very helpful and efficient. The lication is good, though somewhat limited since it is near LHR. Noise from the airport was minimal. The breakfast was good. The building seems in good shape, though it is a bit dated in design. Plus, there is no elevator (which they are clear about, so no surprise); but, that can be difficult for people with mobility issues. There is plenty of parking!
My biggest negative: since it is an airport-adjacent hotel, guests tend to come and go at all hours ... and frankly are rude (noisy, talking on cellphones in the hallways, etc.). This isn't the hotel's fault, but it does detract.
