So many options of places to stay but for self-catering, this seemed like the best option. I have a serious gluten allergy so staying at a place where we can cook a proper meal (daily) is a must. It had everything we needed in a large studio apartment. Everything was high end and worked great. We walked to the V&A waterfront a couple of times and there is a DisChem just down the street for convenience. We brought everything else with us which is good because there was no coffee, sugar, salt, pepper, etc-but we had it already. With free parking in a covered lot and 24/7 security it was really a great option. The gym, pool and bar were also nice options. We would stay here again 100%.

This hotel has gorgeous views facing table mountain, but the rooms are rather small and there was always some noise from renovations during the day and people returning and slamming doors at night. I was repeatedly approached by beggars outside the hotel. Breakfast was ok but unimaginative.

One of my favorite places to stay in Cape Town. Rooms spacious and clean, perfect for family or business vacations. Close vicinity to Waterfront and easy access to highway for traveling to other areas. Great restaurants available in hotel for all meals.

Unfortunately we didn’t have a good experience like others seem to have had. Check in was quick but as we walked to our room, we heard loud banging in the rooms near us (partying) and the room next door reeked of weed. I complained twice about the noise which quietened at 11:30pm. In the morning I went to the spa and gym. There were no visible sanitizers at both facilities. Nobody present at the spa to take my booking either, so I just left🤷🏽‍♀️the rooms are spacious and lovely but I’m just unimpressed about the above.
