Best option might be airbnb, or cheapest might be a shared house (use google).
There are "weekly mansions" (= apartment) which may be furnished, but they are quite expensive.
Alternative would be an apartment but usually they are rented out for a year or more. You have to pay a fee of 1 months rent (or more) and also a deposit of 2 months rent (some of which may be returned to you when you leave, depending on how much is taken for cleaning). A small apartment might cost from 600 euros upwards (70,000 yen) a month. You normally have to buy furniture (fridge, vacuum cleaner, futons, possibly a cooker and other kitchen stuff), so it would be a hassle for a stay of only a few months. 7 months agoAnswered by niall via WorldNomads.com
