I have been living in an apartment complex that has not had any windows for the past six months in either one of our bedrooms I have two children ages 5 and 8 that has not been able to sleep in their rooms due to the fact it is to cold. there is a lot of glass on the ground outside of our apartment that we have asked to have cleaned up several times. my daughters stepped on a piece of the class that went through her shoe and stabbed into her foot causing a good size cut on the bottom of her foot. we also have a huge holes throughout the whole building in our complex. I have contacted the apartment complexes regional manager and they have asked me what kind of compensation I felt I was entitled but I have no idea what to tell them or if we should file a lawsuit.
