If i was to live in an apartment now I would definatly live on the first floor....with 2 children that RUN and JUMP ALOT I wouldn't wish that on anyone who lived below me LOL
I have lived both on the first and second floor while raising two active sons. yes, you do have to think of the people living below you but in most cases you can reach some kind of agreement on when too much running and jumping is just too much. and as an afterthought...heat rises. it was much cheaper to heat my apartment when I was on the second floor
