Penthouse for rent - 8004 Zürich

This is an exchange offer. (Provider ID: 152255)
I would like to exchange for a large, centrally located 3.5 room apartment in district 4. It is located right next to the Zeughaushof on the 4th (and top) floor. It has its own attic, which is only accessible through this apartment. In addition, there is a private washing machine, a large built-in wardrobe in one room, and a courtyard with bike stands.
The tram station Helvetiaplatz is about a 2-minute walk away and the main station (HB) is about a 10-minute walk away.
Right outside the front door, there are many bars, restaurants, and shopping options, as well as a large green space of the barracks area.

My request:
I am looking for a comparable apartment in districts 2, 3, 4, 5, 6, 7, and possibly 10.
I look forward to your exchange offers.
