My partner and I rented the whole unit for our trip, but it was a good size for just one couple as the lounge area can fit up to 4, but it comfortably fits 2. The unit is located in the backyard behind the main house, and there is a secondary unit off to the side. None of the places share a common wall though, just backyard space.
The kitchen was well stocked, Maree even contacted us ahead of time to ask what type of bread and milk we preferred, which was a nice touch! She was very easy to communicate with and showed us around the unit when we arrived.
The only thing to be mindful of is that the unit is accessed through a side gate that can only be opened from the inside. It seems to be mainly left open during the day while someone is home but it gets shut at night so you'd have to coordinate with the Maree if you were expecting to come home very late.
There is a bus stop at the end of the street which made getting to the city very easy. The bus trip was only 20 minutes.
Overall we had a very pleasant stay, thanks Maree!
