My partner and I enjoyed our six-night stay at Nick and Tanya's loft. As this was our first trip to South Africa, we found their loft to be very secure (including the parking facility) and conveniently located to all points of interest (Table Mountain, Lion's Head, downtown, waterfront, Camp's Bay, etc.). The immediate surroundings also offered a great selection of museums, cafes, restaurants and bars all within walking distance.
While we were admittedly at the loft over New Year's Eve and know that this can be an exciting time for any city, we did find the street noise to be bothersome at times. The loft itself faces a main artery into downtown and the large windows do not insulate from the outside noise. Definitely not a deal-breaker and would stay again, but just wanted to note in case anyone is a light sleeper and is considering the loft over a major holiday.
The loft itself was well-stocked with everything you could possibly need. Nick and Tanya were the consummate hosts and very communicative. We would definitely consider the loft when we return to Cape Town!
