So, my advice is, always try to get private lodgings. In tourist towns look for the words NOCLEGI, POKOJE and suchlike.
In general I can but echo what has been said.
I also prefer pentionat, agroturistica and guest houses, these are much more welcoming and landadies do want to spoil you.
Also found most motels are good value especialy if you need a one night stop on the road to whearever.
The ones to view before you agree are the NOCLEGI offers, in general migrant workers occupy these as cheap lodgings and can be a little too basic but O.K. for a place to flop....:0)
