Airport? 10ish minutes away by bus. City? 45ish minutes away by tram. It was more important for me to be close to the airport for an early flight, so I had no issue going in and out of the city (the all day passes are very reasonable).
Bed was extremely comfortable, extra pillows, snacks and sparkling water waiting for me (and replenished after I had left and come back). SUPER fast response times.
If you’re going in and out of the city, be sure to download the Bahn map apps in advanced - it will be a life saver!
