I really like the Rosemont area, especially compared to Schiller Park where I used to stay during an O'Hare overnighter.
When I first got there I was rather surprised by how small the lobby and check-in area were, considering that this is a ten-story hotel. It wasn't a problem at that time [~2100], but a few hours later it was very crowded.
Medium-size room with wet bar. fridge, microwave, and coffee maker. Bed was comfortable but the two pillows were flat and not very supportive. The room was immaculate and well cared-for. Good selection of cable TV.
On the ground floor you will find Harry Carey's bar and restaurant. I was there on a Saturday night and the bar was buzzing with activity. I met a few interesting characters that night. It isn't cheap though, and bring cash or credit cards as they claim to have no affiliation with the hotel itself, you cannot charge anything to your room. The next door restaurant had an impressive menu, but the prices were definitely NOT impressive. [$$$]
There are other hotels and bars within walking distance, but I wasn't in the mood when it was sub-freezing outside.
When I booked the room in advance I was quoted $89 rate, but when I checked-out the next morning I was charged $119. I don't know why it happened that way, but the desk clerk quickly fixed the error.
I would definitely recommend this HI, depending on how much they charge you.
