We had an amazing stay at Kathy’s place!
She was very friendly and always proactive (gave us a a lot of recommendations and always helped immediately when we needed something).
The apartment was very big for 2 people and had everything we needed. Even during load shedding we still had wifi, so that wasn’t a problem either.
The only tiny thing you should know in advance is that there is no AC. Hence, it’s quite warm at night (there is a fan though, but we didn’t want to use it in order to not catch a cold from it) but if you open the windows, it's quite loud at night - mainly due to a construction site and a mosque nearby (4-5 times a day you can hear the adhan). However, this shouldn’t be a big problem if you just use earplugs :)
All in all, we would highly recommend this place and definitely come back!
