Rental apartments

[AnnaLeo]

Hi there,
I am moving to Oakville due to some personal issues. Our house has given an immediate notice period for vacating. We were in a hurry and booked a rental apartment in Oakville near to the lake. But I have some queries regarding the rentals. Initially, we planned to rent a single bedroom apartment for 3 members but I had thought, sometimes our family may grow and it may be difficult for us to live there. So would it be better to choose 2 bedroom apartments? Here are the details of the apartment www.macsuites.ca/oakville/condos-of-oakville-ontario/, do we need to book the 2 bedrooms suite? How could we arrange the single bedroom apartment for 3 members?
