I am here during summer and winter holidays (June/July/August/December), but my parents can host you almost the whole year. There are two double beds, one single bed + two more single ones if me and my sister aren't at home. My home is 2 km from the airport Katowice-Pyrzowice, and we are also near to Katowice, Oświęcim (Auschwitz), Krakow (1.5 h), Wrocław and Polish mountains. Me and my family will be really happy to host you, show you Poland, and hear stories from the whole world!
One small notice: my parents don't speak English, but in spite of that, they welcome any guests, and they have some experience in international hosting ;)
