I always stay at the Hyatt Place Milwaukee Airport when I am in town on business. It is perfect for the business traveller. Customer service is always great, serving food, coffee, and cocktails 24/7. They have a business center, fitness center, guest laundry area (so important for longer stays!), pool, and a very delicious breakfast each morning. The rooms are very large (~400 sq ft) with a full size couch (w/ pull out bed) and large desk. The hotel is very reasonably priced.
I look forward to staying at other Hyatt Place hotels in future business travel.
