Hi. I came to Kiev from Lviv 2 days before by train. The train was very comfortable and new. There was free Wİ-Fİ. It came to Kiev 5 hours. Kiev far away to Lviv 600 km. I paid 450 grivna, namely 18 USD. But it was first class. Normal ticket is 330 grivna. If you want to go to Kiev - Lviv you defenitely use express train.

So Kiev. I very like it. buildings, people foods all of them very nice. Same time very cheap. A bit cold but not important :)
