Tausche 4.5-Zimmer-Wohnung in Zürich, Kreis 2

[INTERNAL STAIRS] We are (sadly) leaving our 4.5 in Enge (museum rietberg tram stop) because we need to downsize to a 3.5. The apartment is maisonette style with 3 bedrooms and 3 toilets overall, out of which 2 small bedrooms with low ceiling and one toilet upstairs, while downstairs you can find one big master bedroom, two toilets and a huge common space with kitchen and big balcony overlooking the lake. The rent is 4300, plus 250 of expenses. For families with kids: please note that there are internal stairs between the master bedroom and the smaller bedrooms. Among the pictures you can see both the apartment with current furniture as well as the original pictures from the rental agency. We are looking for a nice, well connected apartment in a central area with two bedrooms for WG.
