3 rooms house of 151 m² in Toronto

I have a four storage townhouse at the west end of North York, Toronto. Four bedrooms are on the 2nd floor and the 3rd floor. The kitchen is on the ground floor. Without any children or parents living together, my husband and I are planning to host 3 students using the three spare rooms on the 2nd floor and use the downstairs for fitness space. My husband works in a restaurant, so he usually does not eat at home. I am a full time Accountant working in a public company. As my office work requires a lot of time facing to computer, I would like to spend more time with people and home chores during off-work hours.
