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.

Very impressed with all aspects of the hotel. The staff were amazing and friendly. The cafe and the Yu downstairs were a great amenity to have. Suggestion to put electrical adaptors on at least 4 the outlets throughout the rooms. We had international adaptors but we still needed the main one.

Clean and spacious room, with a full kitchen (although I didn't use). A complimentary bottle of wine upon checking in, as well as 2 bottles of water daily are provided, which is a very nice gesture. One drawback: the wall outlets are generally not suitable for most international travelers, but it should be easy to borrow an adapter from the front desk. Breakfast is decent, and the Chinese/Japanese restaurant at the hotel is pretty good. Other than that, one needs to go a bit farther distance to find good restaurants.
