Hannah's place is great for couples or friends visiting Cape Town. It's clean, in a great location to get around to all the sites, and is safe too. Hannah herself is also very helpful with suggestions for things to see and do, and general communication about the flat.
The only issue we had was that the air conditioner wasn't working, but we reported that to Hannah and she was quick in responding and is trying to fix it. It wasn't a problem for us as it wasn't too hot yet anyway though.
Please also note that there is also a lot of street noise at night, particularly on weekends, so it isn't necessarily the best place for light sleepers. Its a main road so it's mainly honking cars throughout the night, but also music from Maggie's cafe downstairs on Friday/Saturday.
Overall though the flat was great for our needs, and we enjoyed staying there for just over a week.
