Kelly's place is perfect, clean, newly renovated and centrally located. There are many, many walkable places to eat and enjoy. There are two grocery stores very close walking distance. The beach is less than a 5 minutes walk. The central business district is a ten minute drive, like 5 USD on Uber. So sightseeing and clubbing/bars are very accessible. I did the cheesy tourist hop on hop off tour bus and they had a stop at Milton's beach which is the closest one to the house. (It was a great value by the way)
Kelly is amazing and extremely hospitable. Makes every effort to insure you have a great stay. She is a gem, I travel a lot and I felt at home at Kelly's place. She interacts at whatever level you are comfortable with and is always available for questions especially where the best restaurants are.
Don't let the water crisis scare you away, it's totally manageable. I would consider it something I was mindful about but not to the point of inconvenience.
Capetown is beautiful, Kelly's home is wonderful and Kelly is awesome. So enjoy!
