This is an 8 bedroom house over 3 floors. 2 rooms on the ground floor (1 of them is en-suite) are rented to professionals or students. Me and my husband are both working mostly from home. We have 3 children(7years, 4years and 2 month old). We live on the first floor and hence no possible disturbance on the ground floor. There is the kitchen and living room on the ground floor. The 3rd room on the ground floor has additional fridge, freezer (for the use of both room renters)
