Our stay began with a 30 minute dispute at the front desk over rewards points. We were shocked at the unprofessionalism and rudeness of the staff not only at the desk but on the phone when they had us call 1800 Marriott because they couldnt even handle our question.
When we got to our room it had an overwhelming smell of cigarette smoke. it was disgusting. All the way down the hall smelled like it as well. When we told the staff we were told " there is nothing they can do about it" and offered us Febreeze.
The air conditioner was extremely loud when it kicked on and kept my kids up half the night.
The breakfast was very gross and we walked around for a few minutes looking for a clean place to sit or even stand and I ended up throwing it away and leaving.
The pool area was dirty and again, crowded with smokers. If you like cigarette smoke this is the place for you.
Otherwise, go anywhere else- I was tempted to sleep in the car.
They share pools with the Fairfield Inn next door and that wasnt any cleaner. If you are passing through, just skip this whole exit.

I had to be in the Dayton area for a few days and we had potentially 2 other couples joining us for a day or more. The room was perfect and significantly cheaper than the Residence Inn in Dayton. We only made breakfast one morning but wished we had all 3. The ladies running the breakfast were so sweet.

We had a little trouble with the front desk staff after a failed movie order and while trying to split the bill at checkout. Both situations were resolved but a little more difficult than necessary.

Satyed over christmas (2010). Without a doubt wonderfull, friendly, caring staff. Spotless rooms, comfortable beds. Quiet. A keeper

This Residence Inn is not at the top. It is not well run and although full often, there are better choices off Exit 74 of I-75. The rooms are spartan compared to other Residence Inns. The food both for the evening meal and the breakfast are poorly prepared. Although it is a no-smoking facility, the night clerk I have checked in with three time over the past four months is a heavy smoker and your room key folder and anything else he handle reeks of cigarette smoke. There is not ample parking to check in - you must take your chances with handicap parking or park around back and walk 250 yards.

Simply put, there are 4 or 5 other choices in the area, And if you want real quality, stay in any of the hotels nearer to Dayton - they are all much better.
