Apartment for rent - 8003 Zürich

This is an exchange offer. (Provider ID: 327145)
I would like to exchange my charming, bright 2.5-room old apartment in a lively neighborhood in district 3 for an apartment in a quieter corner (preferably also district 3). The apartment is bright, has a small balcony, and very uncomplicated neighbors:-)
The apartment is best suited for a single person.
Washing is uncomplicated, without a washing plan.
A rather small cellar compartment is available.
The apartment is on the 4th floor, without an elevator, so including fitness training:-)

I am looking for an apartment with a balcony in a less lively corner, preferably also in Wiedikon, but I am open to discovering new neighborhoods.
