We stayed in the Groot Constantia Villa for a week with 8 adults and one toddler. The villa was perfect for us: it had everything we could wish with excellent facilities (including a private pool, sunbeds, bbq, wifi) and is situated in a beautiful area right next to the Great Constantia wineries. The house is very large and luxurious (easily sleeps 10 adults), and cleaned daily by the friendly staff. Dennis (the owner) gave us a lot of tips and was very helpful. When we said we were bringing a 1 year old he bought a cot and toddler dining chair.
We highly recommend this villa!
