Commercial building for rent - 8700 Küsnacht ZH

I use my office in the basement with 3 workstations only 2-3 days a week and even then only for a few hours. I would like to share it with someone uncomplicated. Either on fixed days for sole use or flexibly for joint work. If desired, also monthly with a monthly notice period. The 35m2 are divided into two rooms, but without a lockable door. Some furniture can possibly be installed. There is running water, 3 desks, a meeting table, a sofa bed, fiber optic internet/telephone. Toilet in the hallway. Parking space. Near the lake. The price includes all additional costs such as electricity/internet/parking/cleaning bi-weekly. If the office is rented monthly for sole use, the price is CHF 900.-.
