Apartment for rent - 8006 Zürich

This is a swap offer. (Provider ID: 334445) A beautiful 3-room apartment, terrazzo and herringbone floors, paneling, small garden seating area, very quiet and central location (10 min to HB, 5 Limmat-/Schaffhauserplatz), pleasant room climate, quiet friendly neighbors. I am in my mid-30s, a busy academic at the university and would like to move in with my girlfriend (also a busy academic at the university) and her children (12 and 10), therefore looking for a 5-room apartment. I have a good relationship with my landlords, but have not yet discussed anything regarding the apartment swap and just want to see what would be available. The 80 m2 area is an estimate. Best regards.
