We enjoyed visiting Zürich and staying in Cher's apartment. We can fully recommend the apartment: it has plenty of room and is very well equipped and we liked the style (and the 55 inch TV with ApplyTV ;-) ), it is well situated to visit the city, bakery and supermarket across the street, close to public transport.
When we come back to Zürich, we would pick this apartment again!
(As the tram is passing the building you may have to close the window during the night in one if the bedrooms, but this was not a problem for us.)
