It is nice place and comfortable place for 4 people. But overall apartment isn’t huge, so keep that in mind.
Location is good but depends on your needs. Tram is nearby and you can easily get to Zurich HB in 15 minutes. But if you need local trains it is quite far away.
Room is also a bit noise as house is old. If you are looking for a quite place, it might not be the best option as you can hear neighbors sometimes.
Also keep in mind there is no hot water after 11pm until morning.
