nicer houses and people driving nicer cars in Vilnus than even Warsaw
that could be an effect of greater stratfication (the richer are richer and the poor are poorer).
I've only been in Lithuania once for a couple of days a few years ago (flew into Vilnius train to Kaunas and back) the cities seemed broadly comparable to Poland (maybe a half-notch behind) but the countryside... it was very pretty but most of the houses looked oooollllddd and like they'd fall down if you breathed on them too hard. I think there's probably a similar gap between cities and the countryside as in Poland, maybe a bit more extreme.
Kaunas was okay but in terms of service was mostly like Poland over 10 years ago, very curt and uninterested in customers....
