Whenever I find my company has booked me into a Hilton I am immediately wary. Yes, they have a grand history and worldwide brand recognition. In my experiences, they have tiny rooms and inflated prices.
The Hilton Hartford changed that for me. Yes, this location hasn't been recently renovated, but it was the most pleasant stay I have yet enjoyed.
My colleague and I arrived from the airport to a warm (and somewhat cheery, camp) welcome from the front desk staff. Upon entering my room, I was immediately pleased to see a normal sized hotel room. The decor is a bit dated, but everything was clean and well maintained.
The only unpleasant event during my stay was not at the hand of Hilton. It is a pet friendly hotel, and one of the guests left their dog in the room unattended. This is a no-no. The poor pooch whimpered and barked for 2 hours until the owner returned. My only suggestion to the management is to be more proactive about contacting the owner and/or removing the pet from the room. Besides distressing the pet, the noise bothered every other guest on the floor.
You will find the location great - especially if you are attending the XL Center. And it is within just a couple of blocks of many restaurants/bars/pubs.
