not sure what your exact requirements are but the house next to us is just coming up for rent. It's in Freienwil about 15 minutes from Baden.
Townhouse over 4 floors, 3 beds, underground parking, would guess it's going to be around 2500 CHF, it's new modern and and very nice in a nice quiet village.
It's not even on the agents website yet but when it is this is their website
