It will be hard for you to find two better hosts than Dwight & Cheryl. They have a beautiful Victorian home with nicely appointed rooms. The house is very well kept, clean and tidy. Dwight & Cheryl are happy to tell you about Saint John, what to see, where to eat, it's very apparent that they are proud of their city. They serve a great breakfast that includes juice, coffee, fresh fruits, stuffed french toast and waffles, topped with real whipped cream and maple syrup. I want to visit Saint John again just for their breakfast!
The B&B is located a short walk to everything you would want to see in Saint John. There are three parking spots in the alley on the property, so you may need to play musical cars, but there is plenty of free overnight parking on the street. On our visit the other guests were happy to move cars as needed.
My opinion is there is probably not a better place to stay in Saint John, certainly no better hosts!
