Multiple rental properties and personal use

I own two condominiums.  I live in one for six months and the other for the other six months.  One is in the US and one is in Canada so when I am in Canada I am there as a tourist not as a Canadian resident.  When I am there I have room mates that I share the apartment with and when I am not there I rent the entire apartment.   My question is how do I enter this on Schedule E since I fully rent some times and rent rooms the other times?  I know I cannot declare a loss and have to carry forward losses because I use both properties more then 14 days.  

 

Can I treat it as 4 properties?
