It has been many years since we have traveled to Germany, but we are considering taking an LTU flight to Dusseldorf from USA. Was wondering where the airport is located in relation to the city and whether there would likely be "Zimmer Frie" type lodgings available in the area.? MY partner is second generation German and would like to practice his language skills in a small family owned lodging if possible. We eventually are thinking of going via train to Amsterdam but would kike to experience Dusseldorf without having to stay in an airport hotel. How far is the airport from the city?
