Staying at Lidija's was an amazing experience! Zurich is a very beautiful place, and public trams were incredibly easy to use, right at Lidija's door (we highly recommend getting the unlimited ZurichCARD pass). Lidija was friendly and incredibly kind, and let us use anything in kitchen and even looked after our suitcases for us after we'd checked out on the last day (so we could pick them up in the evening without taking them all through the Zoo!).
Oh, bonus tip - Zurich has incredible water fountains every where - absolutely no need to buy bottled water, you can just fill you bottle up. :)
