We enjoyed a short stay at Dayana's with our 10 month old on our first trip to Zurich. The apartment is well situated in a beautiful district, has everything you need and is close to excellent public transport. There is a bit of road noise but what you expect in a city (?), and contrary to the odd other review, we liked hearing the nearby church bells which did not disturb ours, or the baby's sleep one bit. Dayana was even kind enough to come and greet us/ensure we got into the flat ok on our arrival in one of the heaviest rain down pours I have ever known (and that's coming from someone who lives in the UK)!
