MEININGER Hotel Berlin Airport is just 1.8 mi (3 km) from the airport and offers a shuttle (available 24 hours) for EUR 3 per person roundtrip. You can visit the 24-hour fitness center for a workout or unwind with a drink at the bar/lounge. A rooftop terrace and a snack bar/deli are other highlights, and rooms offer flat-screen TVs and free WiFi.
Pros: Everything, but the location.
Cons: How isolated it was from the city. I got off at the train station and walked for 10 minutes in the dark to get to the hotel.
Pros: I like that the hotel is very close to the airport and that there is a grocery store in the vicinity.
