Monthly mansions and serviced apartments may not be new to Tokyo living, but in today’s less than- certain markets, they are used more and more by executives and companies struggling to house their employees, and are also a simple solution for a transition period while downsizing your apartment. The benefits of these types of apartments are numerous and include no key money, no large deposit required (usually one month in advance is sufficient), full furnishings, and in some cases, services. Some even include the possibility to extend your stay by the week.
