I can't recommend the Old Church House Inn enough. They have one room that gets half of the church to itself: a downstairs living area, the bedroom upstairs (with a very soft bed), a bathroom with jacuzzi, and a sitting area.
The owners, Dean and Holly, are what take takes this bnb from lovely to fantastic. They are warm and attentive, while giving you space to relax by yourself. They add small touches that make all the difference. Classical music plays softly (very softly, not irritatingly) in the living area. A little plate of freshly baked cookies waits on the desk in the sitting room. At night, a handwritten weather forecast sits on your turned down bed.
Breakfast is delicious! They asked about any preferences, but as we didn't have any, we were greeted by surprising and delicious meals. Fresh fruit and entrees with great and interesting flavor combinations (cream cheese herbed eggs with crispy bacon, fresh popovers, oven baked apple granola).
Although it isn't located in main Peoria, it is really a very short drive to town (less than ten minutes to Peoria Heights). If you are visiting Caterpillar in Mossville, it's really only two minutes away.
