My husband and I are frequent visitors to Duluth and this is our favorite place to stay. We always book a canal view room as we love to watch the ships come and go, no matter what time, day or night.
The rooms are clean and comfortable. Tastefully decorated. The up stairs rooms have just enough area for two people. If you prefer to spread out a bit I would recommend the lower level suite. It has a separate bedroom, wet bar, and large living room area with fold out sofa. Perfect for when you have more than two people staying.
Some things they could improve on from our last stay... Should upgrade the pillows, a bit small and turned into a bag of sand in the middle of the night. Stock more towels in the bathroom. With the jacuzzi, guests will go through more towels.
Coffee and Continental breakfast is available in the lobby. We usually walk across the bridge to get breakfast but have stopped in for coffee. Nice amenity.
All in all this is a unique place to stay, no better view of the ships and the beautiful Duluth skyline. You can watch all the Canal Park action from your balcony.
We will continue to make South Pier Inn our "home base" when we stay in Duluth.
