I am a young central hostel next to the station Berliner Tor in hamburg. Near me there are a lot of restaurants, bakeries and supermarkets. I am just:
One station to main train station (HBF) : U2, U3, U4, S1, S21. Or 10 minutes walking to there.
500 Meters away from main bus station (ZOB), walking 5 Minutes.
24 Minutes with S1 to the hamburg airport.
