Dale and Fran's flat was in a great - really, great location. It's small but has everything you need for a comfortable stay. No wi-fi directly from the flat but the building has wi-fi that you can pay for.
Right across from the V&A Waterfront, loads of bars, cafes and restaurants nearby, walkable to Long St, Bree St etc.
It was a good place to be to see a lot of Cape Town and beyond, and Signal Hill is right behind you!
Only slight downside is the noise from the surroundings but you are in a busy part of the city so you have to expect that.
Make sure you go to Shift cafe as well :)
