We spent a night here. We got a great deal, it was like $150 and that included valet with in/out privileges ($40) and 2 tkts to the Field Museum ($50).
The room is a little on the small side, but it's very clean and the staff was very helpful and friendly. The hotel is located 2 blocks from Michigan ave. There are no restaurants in the hotel, but there are a bunch of good ones nearby.
We were very happy and definitely will look to stay here again in the future.

The Fairfield is clean and newly renovated, with an attractive (if minimal) lobby. Free WiFi is available in the lobby and the 2nd-floor breakfast room; I also managed to find some other WiFi from my fifth-floor room. Breakfast is good, as free hotel breakfasts go. If you've got business downtown, the location can't be beat. Very firm and comfortable mattress. Friendly, helpful staff. A great value for the price!

Chicago's Marriott Fairfield was a great place to stay on Magnificent Mile without paying a mortgage payment for four nights. I have stayed in more than 5 different hotels in downtown Chicago (I prefer 4-5 star hotels). The average price is at least $350 or more per night. However, I have never visited Chicago in November and it seems that the okay hotels wanted more than $300 per night and the luxury hotels wanted $499 and up per night which is absolutely crazy unless you are a "rock star." If you are a parent visiting your college kid, all of your money is needed to spend on your struggling college student (smile). The hotel was very very clean, staff were very polite, the continental breakfast was the best and inclusive in your daily room rate. And, if you are driving and need to get to the expressway, it is a straight route to major thoroughfares.

I am glad that I decided to stay at the Marriott Fairfield and would definitely stay again. It was in a great location. And for those folks who gave the hotel a low rating, they are probably unhappy in their lives and are a pain in the ...................... for most people they meet. Also, I've stayed in many European hotels that were more costly and much much smaller. In comparison, the room was like a suite and the beds more comfortable.

Stayed for 6 nights, and thought it was an ok hotel in a great location.
To find good hotel deals in Chicago is not easy, I learned that even an ordinary hotel room can cost more than $400 a night, which I find absolutely insane.
This hotel was the cheapest Marriott option in town. We paid around $250 per night, not too bad.
Continental breakfast included.
The room was nothing special. The interior was nothing to write home about, but the bed was comfortable (Marriott's beds are the best).
The room was of standard size, but I guess small for american standards.
Desk staff seemed very busy, and not particulary helpful. They seemed almost annoyed when asked a simple question. When we asked for an adapter they just gave us an adress where we could buy one. I think it is very strange that a hotel in a major city don't have adapters.
Anyway, we loved the location, walking distance to many of the main attractions, including Navy Pier, and would recommend this property if you do not wish to pay the ridiculous prices some of the other hotels are charging.
