My favourite place in Poland is Morskie Oko. It is in the vicinity of Zakopane City. It is a lake among mountains. On the shore of the lake is a mountain chalet*. I like the place beacause of beautiful views.
*I dunno whether what stands at the bank of Morskie Oko is a chalet, because I dunno what a chalet is precisely. Websites of such mountain hostels usually name these shelters.
