Mark was a great host. The flat is lovely - three nice, clean rooms, three clean and well working bathrooms, and a very nice kitchen/dining and living area. There is a great little balcony overlooking Capetown and the ocean which was the perfect spot for breakfast and evening drink.
Mark supplied us with enough keys for everyone, there is good wifi service, free parking outside - we never had a problem finding a spot. There is also a study area in the flat an on a whole it feels very clean, modern and comfortable.
A cleaning lady came while we were staying, which Mark informed us about, which was great. There were enough linen and towels, all clean.
We had a great stay at 21 on Deane and would recommend it highly.
