Wow! What a beautiful, stylish place. Such nice special touches such as the JBL speaker, some board games, huge TV with YT and Netflix, Patio with a BBQ and view of Table mountain, Nespresso machine, Nutribullet, strainer and hairdryers in each room and such a perfect location.
The noise from Long street is inevitable in the whole area, don't let that deter you from such a nice spot. Loop street and Kloof street are also walking distance and holds all Cape Towns coolest bars and restaurants.
We would recommend it to anyone. Also no point in complaining about the noise as this has been raised in the comments already.
