Arrived in Prague via Train from Berlin. HIghly recommend taking the train as its a smooth 4 hour ride with some pretty cool views.
Stayed at another hostel (Madhouse Prague). Its a party hostel so if its that your thing but the location was nice.
Day 1 - 5: My time there was spent doing walking tours that i found via the hostel which i highly recommend. The architecture in Prague is amazing. Had lunch with some friends next to vltava river on a gorgeous day which was nice. Visited some castles. The food there was alright, nothing to write home about. Prague is not a large city, looking back 3 nights should be more than enough to see the main attractions. Unless you have day trips planned to other part of the country.
