Mostly, lodging is divided into three separate categories: full service, limited service, and extended stay. Different places will offer different hotel facilities and it's always good to know what to expect to get the best for your dollar.

The extended stay is exactly like that, a place where a person can stay for a long time and get a very reasonable rate. They offer limited facilities that are very useful for people who move and do not have a place to live in. Mostly, you will get a clean room and very few others.
With lower prices, very little is expected in terms of services received. They will usually offer to housekeep once a week with the option to pay for it if desired more often. Although there may be a swimming pool, that is very unlikely, they will offer laundry facilities on property for their guests.
Limited services have changed a little over the years and they offer more value than now. This is a very profitable niche in the hospitality industry and while owners want to stay that way, they now offer services they have never done before in an effort to make cheap-minded travelers switch from full service to limited services.
Many small things will be served on limited services, such as housekeeping, and some properties will offer a free continental or hot breakfast for their guests. There may be restaurants on the property, but it might be more of a cafe style meal. Although the pool is sometimes available, it is usually an exception and not a rule.
