I accidentally booked this hotel when my conference was actually at Hilton Phoenix Airport, and I'm so glad I did. The HGI is much more modern and comfortable than the Hilton Airport. Everything just looks fresher. HGI wasn't your typical depressing airport hotel. The hotel staff was all friendly and accommodating.
There was an in room Keurig, fridge and microwave. The Keurig pretty much made it for me. The room was large and comfortable and easy to work in. The wifi was free and worked well enough. I received a free made to order hot breakfast voucher, and it was actually pretty tasty. The bed was ROCK hard but I actually slept pretty well so I shouldn't complain.
Some reviews mentioned the sketchy area but I didn't notice anything, or feel unsafe as a single traveler. Crudo is an amazing restaurant only 3 miles away.
I try to stay at Hilton properties when traveling for work, but this was my first time at a hilton garden inn and now I'm a total convert.
