I have an underground parking spot available for rent from beginning of October 2015 until the end of March 2016 (six months).
Location is in Kreis 5 on Josefstrasse (corner where Motorenstrasse meets Josefstrasse), very close to Röntgenplatz and Limmatplatz. It is on the second underground level of an apartment building.
Available for CHF 230 / month.
PM me if you want to come check it out or are interested in general.
