I remember a night stop years ago when in Gulf Air in Zurich as at breakfast I was reading my Daily Telegraph and did not notice that there was a lit candle on the table until my paper burst into flames!
I lived in Zurich for 10 years. Hotel? Hard to say, the Movenpick in Glattbrugg should be alright. I only know the bar there, which is worth a visit. The Jules Verne bar is on top of a tower in the middle of Zurich, if you get a table at the window, you´ll get a great view on the city! If you have enough time and the weather is reasonable good, I recommend taking the train up to the Uetliberg, local mountain (or rather hill for Swiss standards) of Zurich. You´ll get another great view on the city, the lake plus the alps and it has a nice restaurant up there as well.
As everyone knows, Zurich isn't cheap, but with a bit of research you can get by. I've stayed twice at the Hotel Otter, above a bar/restaurant and each of the rooms is very quirky, but nice, priced way below many of the other hotels, downtown. If you're staying 5days make sure to buy a tourist pass and do lots of breathtaking day trips to various mountain towns, though appropriate clothing will be needed to stay warm! No 'leaves on the line' or 'wrong kind of snow' in Switzerland and the SBB functions like clockwork all year. Have fun!
