Description

New England/Queen Anne style Victorian home situated on the south bank of the Illinois and Fox Rivers featuring 3 levels of incredible river views. The property sits on the banks of the Town of Two Rivers in the Heart of Starved Rock Country! This home is full of character, leaded glass windows, three fireplaces, vaulted ceilings, spacious bedrooms, and a living room with french doors to family room. In the back, there's an outdoor sauna and a carriage house that offers a 2-car garage plus a second level heated rec room. New slate roof and copper gutters. The property is currently a fully-functional Bed and Breakfast and one of the only ones in the immediate area. Also, turn-key, walk-in-the-door to a beautiful one-of-a-kind single family home! Perfectly located near public boat docks, launch ramps, as well as Allen Park, a beautiful riverfront park. The house is walking distance to the Illinois River bridge and downtown Ottawa's shopping and restaurant district. History is key as the property sits on the once occupied Fort Johnson!

    "Need a vehicle to access most areas of Ottawa. Walking is an option, due to many sidewalks. Ottawa is limited because of only one bridge crossing the Illinois River. The Northeast side of town (where the High School located) is also limited because of only 2 ways in and out. Currently it has only 1 way due to construction. "

    "Sometimes there’s a festival or an event that blocks off roads and sometimes you don’t know when they’re happening so it’s a major inconvenience when you try to get to work and there’s a lot of traffic and no one moving. "

    "There’s a lot of other dogs so if your dog doesn’t like other dogs just be careful. Everyone picks up after there animals pretty well and most of the dogs are nice. A lot of them end up being aggressive with your dog but other than that it’s a lovely place for your dog. "

    "Location cannot be beat. Lovely area filled with unique styles of homes. Not a cookie-cutter development. Quiet, peaceful and friendly. Great mix of people of all ages. Well maintained homes make the North side a sought after location. Believe it or not, there are people who actually did not know this area of Ottawa exists. Close enough to the downtown area if you choose to take a nice walk to the riverfront. Good caring neighbors. Cannot emphasize enough how nice and tranquil it is in this area. Great School District, close to all churches and Ottawa Regional Hospital and Medical Center. Definately a lovely place to live. "
