Look for long term stay hotel's like Candlewood or Staybridge Suites etc.
The longer you stay the better you can negotiate a better deal, plus with those types of places a hot breakfast (7 days a week) and usually a hot dinner is included 3-5 nights per week. So that saves you some coin not having to eat out.
These places also come equipped with a full kitchen so you can buy groceries and cook rather then have to constantly eat out. As well as complimentary laundry again saving more coin.
Hope this helps.
