Stayed for one night at the Crown Plaza whilst working near by. nice hotel with good size rooms. Free use of leisure centre facilities in te adjacent building, I went for a swim and sauna!
To get into central Liverpool plenty of buses go from outside hotel on the main road cost £1.80 each way, taxi is £10.
Would stay again if on business, or catching a flight, but not ideal if your wanting a city centre hotel.

Although I live fairly locally, I needed an overnight stay near to a social function to avoid high taxi fares or driving after drinking. I chose the Crowne Plaza to renew an acquaintance with a building I first visited when it was still Liverpool Airport Terminal in the 1950s !!
Much of the exterior appearance has been preserved, and the extensions have been completed sympathetically to the Art Deco styling.
Reception was good, and the room was sumptuous. The Room facilities were excellent, and the bed was so comfortable, I was lucky to rise before the generous check-out time !!
The Bar service was warm and friendly, and the Snack Menu and food were good.
Again, breakfast service in the Restaurant was friendly and the staff attentive.

A good experience which I would not hesitate to recommend to anyone, and use again myself.

What to do when you have a 1930's hotel? Keep it as an antique museum piece or modernise?
Well if you are going to stay in the 30's, you still need to make sure it's up to standard.
No musty smells, a shower that works, heating that works, beds that support, furniture that's not tired, lack of sound proofing, etc
Unfortunately this hotel has all of these problems and makes no attempt to address them.
Personally I can live with this for a one night holiday "experience" - not so good on a business trip when you just want the functional.
That said, everything else works well but the overall customer experience is lacking

I've stayed here on a number of occasions and it's certainly come a long way in terms of customer service since the bad old days when it was a Marriot. Positives are that the beds are super comfortable, the food/wine is generally good (but very expensive, I sometime head to the M&S express over the road, the retail park is very good for shopping!) I can always get a good hot bath and a decent nights sleep here. Plenty of parking and as long as you are not in the exec rooms overlooking the old airfield not much noise from planes. I like room 208. The only drawback came when I accidentally booked into the city centre crowne plaza - more expensive and the parking charges are a rip off but oh boy that hotel is truly excellent. But if I was paying myself I'd probably take this one.
