First time it happened to me : the airbnb reservation in Harsova is ghostly : I found the address, a lady answered me that yes it was the address indicated but that no she didn’t rent anything or anyone next door ! I had not received any reply to the messages and the phone indicated is to the absent subscribers....
After some exchanges with the airbnb support they cancelled the reservation and found me a hotel that suits me very well !

Otherwise the road had been very pleasant, not a long distance which allows to arrive early (so to realize the problems and solve them early too !).
Clouds accumulated a little at one point but nothing... for me the sky remained merciful :).
