We stayed here for 6 nights as part of a vacation, it was very close to a grocery store (lidl) and also the train station to-from the airport and city center (Dusseldorf-derendorf is the stop near
the hotel, about a 10 minute walk)
If you are vegetarian or vegan, the breakfast is a bit smaller in terms of options, I mostly had just fruit but the staff were very helpful and looked up ingredients for me in the bread products. There are a variety of cheeses, yougur,, ceral (with milk) and hard boiled eggs if you are vegetarian though.
Overall the stay was great, we originally booked a room with a sofa bed as well but only got a single bed, which was fine and we made it work, and the app did say we were not guaranteed this, or the request for extra pillows (as I have bad leg/neck issues I needed them, but we made due)
Either way, the hotel is very affordable, and was lovely. Really enjoyed the stay! [Less]
