Here are some of the things I don't like, but do know that I haven't been to the whole Europe, only sampled a few 👀

• Most shops or restaurants close at 6 or 8 pm, and it feels like dead towns during Sundays or holidays.
• The infrastructure is quite bad in many places, especially airports; seriously, out of all these years of traveling, and I've been to many "less developed" countries, even airports in Vietnam are way more organized than in Amsterdam. 😂
• People are nice but quite distant, aka not really helpful...
• Things are so much more expensive yet with average quality.
• Lack of diversities or uniqueness, most Europeans cities feels the same tbh.

cold, empty, and dull...

Europe is big, the mentioned points mostly being generalized; however, I do like Eastern Europe!
