from Tallinn to Lviv

I start at 1 pm in Tallinn, change the bus in Riga and arrive in Warsaw at 6 am next morning. Lot of snoring in the bus and no hassle at the borders. Spend five long hours waiting for the bus to Lviv. Next long waiting is on the Ukrainian border where all documents are checked three times. And after some driving on Ukrainian soil, we stand again. The reason is not given, looks like some technical problem on the bus.
We still reach Lviv before dark. I find my hostel, take a shower and manage to find a fast food restaurant. Tired.
