My list - Underrated cities in Europe

I have been to almost all countries in Europe and I've decided to make a list of some of my favourite underrated cities. We all know about popular cities like London, Rome and Paris. So I will give you my top 3 underrated favourites. They are not in a specific order since I change my mind all the time.
 
BYDGOSZCZ - POLAND
I had the opportunity to live here for almost one year so I might be biased. But it doesn't change the fact that its a beautiful city. 
 
BORJOMI- GEORGIA
I'm not sure if Georgia counts to Europe. I tried to search for it but every website tells me a different thing. I decided to count it anyway! Borjomi is known for its healthy water and it is truly a beautiful place.
 
 
KHARKIV - UKRAINE
The second biggest city in Ukraine but not even close to being as popular as Kyiv. In my opinion Kharkiv is really worth a visit!
