If you have never stayed at a Residence Inn, it is a great place to stay for a month long project. Trust me, been there--done that.
A month in a hotel with a chair, a desk, the two beds with the remote glued to the night stand in between, and a TV is only comfortable for about a night or two. Residence Inn is a suite with full kitchen and living room...reminds me of home on those long assignments. And you can stock the fridge!
