We stayed 2 nights over the New Year at this cute boutique hotel on a quiet, residential street, but within easy walking distance of the old city of Zurich, and Lake Zurich. We drove down but parked our car (25 per night) and didn't move it again until checking out.
The location was perfect, a 10 min walk from the opera house where we saw a performance our first night, and 10-20 min from the heart of Zurich's old city, depending where you're going, for tourist activities, sightseeing, or enjoying the New Year's Eve festivities all around town. Luckily the rooms have very sound-proof windows, so our dog was fine on NYE, even with all the scary fireworks going on outside!
The hotel is modern yet traditional, with a fun Swiss cow theme throughout. Check-in & out was smooth, and the front desk staff were all helpful and nice. We didn't have cleaning service for our short stay but the maid did offer us fresh towels and toiletries if we needed. There is a small but decently-equipped fitness center, with a treadmill, recumbent bike, some free weights (though several were missing their size mate) and an all-in-one weight machine.
The only negative we experienced was the shower head, which wouldn't fit properly in its holder because of its weight, so you had to hold it during the whole shower. Super annoying, but I don't know if that was just our room or bad design overall.
