We loved every minute we spent at Simone's place - it truly exceeded our expectations. Our party of 9 had more than enough space for us not to feel at all cramped, and the beach being a stone's throw away was the icing on the cake.
The kids had a great time too - there was no shortage of books and games to keep them occupied. I would definitely recommend Simone's place to large families looking for an idyllic beachfront Airbnb in Mandurah.
