Hauptstadt Berlin Stadt !!!!!

Berlin even though I personally have visited number of times before, for my wife and friend it was first time. For the first timers, we would advise to separate at least 3 days 2 nights plan for it.

Travel Recommendations:
1. Berlin Central Station is well connected to every big cities around Germany.
2. Recommend to take Flix Train if you want budget travel and Sparpreis finder from DB Bahn if you want DB Bahn travel. Book as 4 weeks early for good price range. Average cost can range from minimum 29 euros to more than 80 euros. Flix bus can be much cheaper option but the Flix Bus Station is bit far from the central city. The price ranges from 9 euros to 50 euros for the Flix Bus.
3. Book hotels from Check24.de or Bookings.com for cheaper options and try to avoid the hotels near North Train Station.
4. To go to Alexandarplatz, any S bahn train can take you to the station and you can also take M marked street trains to Alexandarplatz.
5. The Neptune Fountain is just behind the tower if you walk upto 10 minute behind it.
6. The dom and Brandenburger gate is near to Main Station. Walk of around 20 minutes.
7. Museum Island is just 10 mins walk from the Alexandarplatz. Sundays are best for free visits in the museums.
8. Take S9 - S11 train towards Ostbahnhof and little walk of 10 minutes is needed to reach the Berlin Wall.
9. Do not forget to try the momos near the Ostbahnhof Station.
10. Restaurants and bars are open till 1 AM in the morning. May be applies same to Döner and Snacks places.

Group Tickets till Zone 2 which can be taken for 2 people and with each additional person have additional cost. Prices are changing every year so its advisable to see it in ticket machine.

All the best for the trip. I hope you enjoyed it !!!!v
