We had Unit C and it was very comfortable for our group of 7 (4 adults, 3 kids (13,11,6)). There are directions on how to use everything. The beds and bedding are incredible comfortable. The bath tub gets nice and hot! The kitchen has all the dishes, utensils, cups, etc. you might need. I do wish there was some coffee available for the mornings, but now we know to bring our own. The surround sound projector TV is cool for access to streaming services.
The location is a 5 minute walk to the train station and about 10 min to a Lawsons. If you have a van, the driveway is a tight fit and you've got to be careful not to accidently go off the little curb separating it from the driveway next to it (there is no lip).
We really enjoyed our stay and would stay here again.
