We had a great stay at the suite, which is located under the main house. It is as described, ie you have a separate / your own entrance, accessible from the patio which opens to a nice garden / backyard. It's located on a drive off from the main roads, in a quiet block surrounded by "cute" properties.
The place was super clean, the beds were comfortable and everything in the kitchen worked as expected. The only negative points are the lack of room to dry your washed dishes next to the sink (maybe a special drying stand off from the sink?), and we were missing some drinking glasses, so had to use the coffee cups; these really aren't major issues, and points the owner can easily address. Fridge, stove, micro-wave, kettle and toaster were all pretty recent and working well.
The bathroom was super clean, you get body wash soap, shampoo, conditioner, towels and more. The tiled shower is pretty large (although if you're super tall you might have to duck), and works really well.
Overall a really good experience! Thank you :)
