I was thinking of the Marriot Residence Inn. Any thoughts?
Always good quality. They specialize in week long stints. I've stayed there as well as "HomeSuites". Check ExtendedStay as well. Most of these places have a guest laundry on the premises. Most have a refrigerator, oven/range, microwave, dishwasher and a few settings of dishes. A TV with cable, a desk, sofa and a comfortable bed. Very livable. A run to the local grocery store to stock the kitchen will save you $$$ over patronizing restaurants.
Compare billing rates on complete weeks vs partial weeks. In some cases you can save money with a full week commitment.
