Renter's compensation?

I am a tenant in a condo and the owner of unit has it up for sale. Their realtor is requesting a scheduled 2 hour window during the week and a two hour window during the weekend where they can do showings every week for an undetermined amount of time. This means a few hours each week where I have to vacate the unit or have showings that will disrupt my privacy, work (as I work from home) and life. Seeing as I how pay rent to live in and use the unit and have to now disrupt my life for these set time periods, is it reasonable to request some sort of compensation for this inconvience? Also, is it reasonable for them to ask for that much time each week for showings? In the past, I have only had to accomodate for showings an hour here or there during the week.
