Lwazi's place it's just amazing! It has a great location, right in the center of Cape Town and near a lot of places of interest (walking distance from the Bo Kaap neighborhood).
The house is well equipped for long stayings and the quality of the internet is good. The only thing that I was very disappointed, was that the host never informed about the loadshedding problem that Southafrica is going through, so if you're a planning to work remotely from here I wouldn't recommend it. The power cuts are around two or four times per day and even the data doesn't work when this happen. So it's something important to have in mind if you're a digital nomad and you didn't know about the country situation.
