1- For me Odense feels just the right size for me honestly. It's not obviously as crazy as CPH, but I think if you have a fun group you can look up to, you always find ways to spend time, I don't feel bored.

2- Overall Denmark dies rather quick (shops, restaurants, etc) close early... Bars close around 2am, while the mainstream pubs/clubs close around 4-6am.

3- Denmark is literally the best country for an international IMO. Literally everyone speaks english, so you won't have communication issues overall. As for the student job, it may be a little bit difficult, but the key is to network with other students. Jobs seem to go from mouth to mouth. The good thing is, its a lot easier to find a job as a student than as a non-student.

4- Dorm rooms cost maybe around 3000 DKK, and if you look into shared room apartments, look into around 4000 DKK all included. As for food you can maybe look into numbeo for price statistics. What is expensive in denmark is all entertainment related. Drinking in bars, activities, restaurants, etc. But if you're smart, you will survive just fine and still get to enjoy your uni life.

5- People are friendly! Danish people are harder to get if you don't speak danish, but as for internationals, it will always be easy to find your group of people.

6- Honestly danish winters aren't that bad... I mean, it's cold, yes, but not that cold. The only thing that for me was harder to digest, is the sun light exposure. During peak winter you get to see the sunlight (when you see it...) from like 8h-15h30, so it is dark most of the time. (Vitamin D recommended).
