We attended a conference at the Cape Town Convention Center right across the street, and so this was incredibly convenient (and much more of a quiet respite than the hotel thus conference organizers chose as their hotel). I would totally recommend this hotel to ANYONE attending a conference at the Cape Town Convention Center.
