I stayed here with my Wife in April 2017.
The rooms are very simple, small, but have everything you may need. The room was quite cheap too so no complaints. Excellent spot right by the lake with views down to the mountains at the south-west of the lake. Free Wi-Fi, although it cut in and out regularly, still free is free.
The friendly people who run the Motor Inn were always helpful when we asked them queries about Taupo, and even helped us doing our laundry. We had one issue where the leg of our bed broke during the night and they were very quick to move us to a new room (with a better view!) with no hassles.
