If you want to pay on monthly basis the price will be 100$ and you have to pay for first and last two months of lease in advance.
Otherwise, if you pay at once for one year the price will be 1000$. (actually you get 17% discount )
Instead of long term leasing you can rent this room for short term. In this case you won't have any time binding. But the price will be 120$ for each month. This option is only available from 1-st of December of each year.
Paid amounts are not refundable.
