Honestly, for a 2-3 month business stay, I'd do my best NOT to stay in a hotel......there are many (many, many) locations that have furnished houses and apartments for short term rent that are often cheaper than a hotel stay and offer much more comfort and space. Some are individually rented, some are run by management companies. Even when I travel for 2 weeks of business, I look for an apartment, house, or cottage to rent instead.
