A colleague and I spent ten nights at Willem's 2B/2B apartment in late October. The location was perfect. A short walk to the International Convention Centre where we attended a conference and a manageable 20 minute walk to the V&A Waterfront. The apartment is on the 5th floor of the Rockwell Hotel which has a restaurant, bar, small gym and indoor pool that can be used by the apartment guests.
The apartment itself offers a well-equipped kitchen, with microwave, full oven, washer/dryer, dish-washer. The TV/Cable system worked well with a good choice of programming. Reasonable closet space for a 10-day visit. The beds were comfortable. Bathrooms were a little tight with a shower in one and a bath in the other - both with toilets - both very clean.
The view from the balcony is superb and looks out over the port and bay.
We were warmly welcomed and shown around the apartment by two of the owner's friends who showed how everything worked and they also pointed out the top tourist things to do in CPT. They recommended some local restaurants such as the Italian (Il Leone Mastrantonio) next door to the hotel which was an excellent recommendation with superb food as was the Beluga Restaurant, 5 mins walk. They also pointed out the location of the nearby Spa grocery store where we purchased breakfast items, etc.
The only issue we had during the entire stay was a problem with the air conditioning which was fixed within a couple of hours and worked well for the remainder of the visit.
Overall: great value, great location, would highly recommend.
