Marius' place is lovely. It truly has all the amenities of home. The view is wonderful and the balcony is great to sit on for a morning coffee or an evening drink. Or you can go up to the 27th floor to get a drink from the bar and meet your fellow residents. The area is really not bad to walk in during the day. Just keep your valuables tucked away and always in front. There are plenty of restaurants nearby or you can get a cheap Uber. You can walk to the V&A Waterfront, the many local museums, or to the Hop-On-Hop-Off Bus for a fun day's activity. The HOHO company even offers walking tours.
Oh, and Marius is truly a good guy. We had a hiccup with the WiFi and he came right up to help and we had a great visit. Great start to our South Africa holiday.
