On my second day I was still at Ballhaus Berlin Hostel. I’d booked two nights separately, so the staff told me to check in again at eight and keep the same bed. It would’ve been a pain to check out before ten and wait until three to get back in :D

The hostel was clean and cheap, €16.93 or a little over 500,000 đồng. There was a bar downstairs, where everyone seemed older than me :D The night before, I’d seen a supercar parked at the door.

It was a 600-metre walk from the hostel to the Berlin Wall Memorial. The wall divided East and West after the Second World War. It went on for quite a way, and I saw one stretch before heading back.

The government office, they're doing some repairs and they have to buy tickets so you'll have to walk around outside.

Looks like a maze, walk around for a while and you see the entrance, free entry, a few minutes later they give one in to a few people.

I wandered around and sat at the station for a while. It was an hour before I took the tram back to my room.

Go to Google Maps to see where we 've been.
Then I bought a train ticket to Hamburg, which was 12.99 euros.

I saw the train ticket here will be cheap in the early morning, peak time will be more expensive, when I search tickets to schedule, the ticket price is 19.99 euros, when you have a visa ticket price increases to 37.99 euro so consider transfer to go FlixBus / Train, to the central bus station is far away, the bus stop at Alexanderplatz is a little closer.
I was planning to buy a train ticket when I arrived because I was afraid of the price increase, but I was lazy, I went the next day, I bought it the night before.
God is not a good man, when I bought the ticket was 12.99 euros, after buying it was only increased, so I went to bed, the next morning on a nice train.
