Morne's apartment was great for our 4 night stay in Cape Town. It's large, clean, open, tastefully decorated, bright, and centrally located. It overlooks Greenmarket Square. This means it can be a bit loud at any time. This wasn't a problem for us since we're city people anyway, but if you're looking for something quiet, this is not for you.
If you are planning to wash clothes, the washer dryer is a single combination unit down the hall, shared by the residents on the floor. There is also no air conditioning so it could get very warm if you stay during their summer season. It wasn't much of an issue for us since the weather was pretty cool. If you are staying more than 2 nights I would recommend asking for a second set of towels as there was only one set for us for 4 nights.
Morne is a great host as well. He communicates everything with ease and replies quite quickly. We thoroughly enjoyed our stay!
