Trip planning

Laptop geeks!!!
Doing some semi last minute trip booking and research before Michelle heads away this weekend!
We managed to sort out accommodation in a few busy places, book a couple of ferrys etc..
I somehow managed to book a hostel in Cinque Terre for the right days, wrong month. Luckily for me the hostel owner is nice and swapped the days for us!!
We are looking for somewhere to stay in Munich from the 20th to 22nd of September (150 euro for a hostel seems insane).. Anyone want to host 4 awesome kiwis?
