My family (husband and 11yo) spent 5 nights and loved it.
The unit is super clean, well maintained with all that you would need for a few days.
Fresh clean sheets, towels and even beach towels.
Francis is easy and lovely to deal with.
The street is quiet as are the neighbours and it's a short walk to the beach road and about a 10 minute walk to the main Cottesloe Beach.
I would definitely recommend this accomodation.
