I had a lovely stay at the appartment for one month. The instructions for self-check-in were quite clear. The appartment was clean and housekeeping came back each week for a quick clean up and change of towels (complimentary). The building includes a community area on the rooftop with a small plunge pool and fireplaces for a braai.
Sea Point is not as quiet as other neighbourhoods like Gardens. However, there are a lot of good restaurants as well as grocery stores (e.g. Checkers, Woolworths) just around the corner. Moreover, the appartment is only a short walk away from the promenade (really recommend a sundown walk there).
Summing up, the appartment is perfect for a long stay for a single person. For couples, it could be a bit too small (unless you do not spend a lot of time in the appartment).
