I also found that web page, but as it does not clearly define the exact meaning of "cunicolare" I did not use this in my suggestion. If you look at the researcr I have done you will find that it generally seems to be used for underground rooms or "rabbit warrens".

This reference about a Castle in Monferrato seems to think it is just a bedroom, but where lots of other things went on as well ... Could the 'cunicolare' mean it is like a rabbit warren, with side-rooms connected to it but not underground or secret ? "Sappiamo che in esso esistevano l’appartamento del marchese e quello del corsone, impertinati sullo camera”cunicolare” cioè la camera da letto, dove si stendevano i documenti pubblici, si ricevevano le autorità e si organizzavano feste" http://www.alboscuole.it/TemplatePRESS.aspx?CI=000Bgalmm0890...
