We used to have these. They were called Apartment Hotels. They’d consist of a single room with a bathroom, housecleaning, a cafeteria and lounges. Imagine being able to rent month to month and not need to furnish an apartment. It was ideal. Nuts we got rid of these.
Lots of people's social & romantic lives could be vastly improved if it was normal for young adults to live in college dorm-style accommodation in city centres until they were ready to set up home properly. Why doesn't this exist? I think there would be a market for it!
