Apartment for rent - 4600 Olten

I am renting out part of my cellar, about 15m2, as temporary storage space. Totally 300.- per month, less area by arrangement.
Windowless room with permanent fresh air supply and automatic Secomat.
Tenant does not receive a key, therefore only suitable, for example, if you are going on a world trip for a few months and want to store your furniture, etc.
Thank you for your interest!
