Hotel promise fulfilled...offers a very clean, comfortable hotel room!
Promise fulfilled -- Hotel promise FROM Hampton Inn Indianapolis Northwest - Park 100 website (on http://hamptoninn.hilton.com/) in the Hotel Accommodations tab, guest rooms:
"Our promise to you includes a clean, comfortable hotel room. In fact, we have 110 of them! If you're traveling with your family, you may opt for a room with two beds. Or, if you're here by yourself on business, why not book a room with a plush, king-sized bed so you can stretch out and relax?"
Pros: 
- Very clean, spacious, comfortable, and quiet hotel room. 
- Staff very helpful and friendly. Housekeeping does an exceptional job at keeping the lobby, breakfast area, corridors, pool area, fitness center, business center, and hotel room clean.
- Very clean pool and hot tub.
- High ceiling and shower head in hotel room bathroom.
- Complimentary hot breakfast with many options. Breakfast area is well kept, even with a lot of guests.
- Located close to I-465.
- Complimentary guest washer and dryer (an unheard of pleasant surprise to me even though I did not use the laundry facility -- located by ice and soda machines).
Cons: 
- Hotel room’s thick end cap decor curtains are fixed towards the right and left sides of window so could not move to keep out most of the outdoor light from the well lit parking lot and early morning sunrise. Please note hotel room also has a white curtain that is closer to the window which did cover the whole window for privacy but was sheer so some light still came into the room with all the hotel room lights off. 
- For all of the amenities this hotel has to offer I would of liked a mini refrigerator in my room. From http://hamptoninn.hilton.com room pictures it looks like the hotel suites have refrigerators, but not regular guest rooms.
Overall, a great hotel in Indy and one of the cleanest hotels I have stayed at.
