Modern comforts and contemporary style at this plush Cape Town hotel - including a studio apartment and breakfast


The Onyx is a pleasingly modern addition to Cape Town's Heerengracht Street - the city's oldest thoroughfare. Contemporary style abounds inside and out here, all the way from the ground-floor restaurant and indoor-outdoor pool, to the plush studio apartments. Situated opposite the Cape Town International Convention Centre, it's an ideal choice for work or play; the city's centre is just a short walk away, and many of Cape Time's historical sights and natural wonders are within easy reach.

The Onyx's Studio apartments are contemporary in style with plush modern furnishings. Measuring 35-52 square metres, each comes with stylish parquet flooring, floor-to-ceiling windows affording city views, an en-suite bathroom, lounge area and fully equipped kitchen.

There's also a deli, so you can stock up your kitchen with quality goods.


There's a modern indoor/outdoor swimming pool at the hotel, from which you can enjoy views over the city, and a fully equipped gym. Sanctuary Signature Spa offers ample opportunity to unwind, with a range of treatments on offer, as well as a sauna.


The Onyx is situated opposite the Cape Town International Convention Centre, in the Foreshore area, just a short walk from the city centre, where you'll find District Six Museum and the Castle of Good Hope, as well as a plethora of cafes, restaurants and bars on and around bustling Bree Street. The V&A Waterfront is a 20-minute stroll away, and Signal Hill (a popular spot for sunset) is a 20-minute drive from the hotel. The burgeoning area of Woodstock, known for its independent art, tech and craft scene, is just a 10-minute drive away, whilst Bo-Kaap's colourful houses can be reached in around 20 minutes on foot.
