It's a nice place to stay, close to the Blue Line that runs all day and night and takes you to Downtown in ~20 minutes as well as to the O'hare Airport in 30 minutes. Also Logan Square is very nice and safe neighborhood, with lots of cafes and good restaurants nearby.
Florida and Justine are both great and helpful. You will share kitchen and huge living room with them. The two rooms for guests are on a separate (top) floor with it's own bathroom and shower.
The cats are also very friendly, but if you want they will leave you alone. Actually, Skinny will mostly avoid you and Fatty likes to be cuddled, but will also leave you if he sees you are not interested. You just need to be prepared, that as there are pets in the house, you will keep finding some fur and hair from time to time everywhere.
