I travel to Islamabad often. In the past, I could not find a furnished ‘extended stay’ option, with access to amenities such as a fully equipped kitchen & self-laundry. My options were to stay in tiny yet super expensive hotel rooms (sorry Marriott), or in some dated guesthouse. Both options did not meet our needs to have a comfort of a home for my family … so I built one for myself … and willing to share with your/your family … only IF you promise to treat it as your own and take care of it during your stay :-)
My house is in sector D-12/2, about 10-15 minutes to many shopping & dining options in sectors E-11/F-11 and about 20-25 minutes from the main downtown Islamabad.
