Miriam Park in St. Paul is full of gigantic old houses, and this is one of them. The 3rd floor is one huge bedroom and a private bath. The decor up there is charmingly antique, like staying at a bed and breakfast. Come and go via common areas, which you can use if you like. The hosts were fantastic and friendly, very easy to talk to. The location is great: high walkability to food and coffee, and whatever else you need is less than a 5-minute drive.
