This is the Covington Inn, a tugboat turned bed and breakfast which sits moored to a dock in St. Paul. This looks like it would have been a really cool place to stay at, but the For Sale signs indicate that it is no longer. Here is an article about the Covington Inn, explaining that it has gone on sale. I am not sure if they are still operating until it is sold or not. Hopefully it will be bought by someone and continue to provide this relaxing getaway right in the city.
