Out of the 2 grad housing facilities, I favor Hasbrouck than Maplewood.
It looks a bit far from main campus, but it is actually not that bad (15-20 minutes walk to school of engineering). Plus the campus buses make the stops at Hasbrouck's Center regularly. You need to pay extra for parking spot, but you will be given free bus pass.
1 bedroom cost roughly $800+/month (not including parking). The cost covers all utilities (electricity, gas, water, trash) and internet (you are given certain quota, I forgot).
A lot of grad students with families live in Hasbrouck. The children's school bus also stops by the Hasbrouck center.
The cheapest housing option in Cornell is if you have roommates. Rent a 3/4 bedrooms apartments and share with roommates. For example, there is an apartment complex (I think it is called Plaza Hills apartments in Pine Tree Rd), which is practically next to a grocery complex. A lot of grad students live there.
Hope this information helps.
