Don't stay here
If I could give this hotel no stars, I would. The Allerton is a HUGE disappointment. 
I travel a lot. I've had better service at the Holiday Inn. Frustrating because The Allerton used to earn the exorbitant prices they charge.
They were difficult to deal with on almost every level – even when tipped very well at the beginning.
Location is good...but... you can get far better service and amenities anywhere else for the price. 
The "service" staff is downright rude - from reservations to the concierge. The doorman was great but that seemed to be a fluke. Most of the staff comes off as extremely lazy. If you need any information - it will not be volunteered. You must ask them to explain everything. They will try very hard to give you the room by the elevators. Dispute it and change rooms.
The front desk will make you feel like you're bothering them. That is, if you can get any four or five of them to look up from their computer screens long enough to pay attention to the fact you’re standing right in front of them. I was ignored for no apparent reason upon CHECK IN. I can't imagine how it will go when I leave.
Be sure to put the DND hanger on the door or the maid will walk right in without knocking as she did to us. 
An absolute must is this: scrutinize your charges. If you must, remind them it's fraud to charge you for services and items not ordered. We had mini bar charges added to our bill when none of the items in the minibar were used. The charges had to be disputed in order to ensure the promise of having them removed. It remains to be seen if they will follow through and actually remove the charges. Get a detailed print out of the room charges sent up to your room hours before check out
On that note, be sure you use your major credit card to pay for everything so you have a leg to stand on when you dispute their "add-on" fantasy charges.
I would not stay here again and I recommend you don't either. It is NOT relaxing to have to marshal your hotel charges, be invaded by rude staff and dispute fraudulently made charges all the way through to reviewing your bank statement well after leaving this place. 
AND it is hotter than an oven through out the hotel.
The Allerton does not know the meaning of service. I'm so sorry I stayed here. Don’t stay here.
