Request for information on Wroclaw ( housing, transportation, general day to day needs) [8]
1. When renting from owner then there is no commission, but for that Polish speaker assistance would be helpful. (you can ask your company for that) When using agency they probably charge something extra.
gumtree.pl/fp-dom-mieszkanie-do-wynajecia/dolnoslaskie-wroclaw/c9008l3200007 - here are many adds, so you may get feeling of prices. Use translate.google.com if needed.
2. I don't live in Wroclaw, but don't think so, as there are nearly no Indians in Poland.
3. Here some comparison of health systems in Europe: healthpowerhouse.com/files/Report-EHCI-2012.pdf
Poland is on 27th place in EU, so closer to bottom, but it's not tragic in most of situations. Generally Wroclaw is considered top city to live in Poland, so access to Medical services should be better than elsewhere. Regarding vaccination you should inform yourself if in Poland is used same medicine. In bad case NFZ (public health insurer) will not cover it and you will have to pay for medicine. In worst case this drug is illegal in Poland.
4. More dangerous than Munich for sure, but saver than most of American cities.
"Wrocław, like most of Poland, is a very safe city and violent crime is very rare.
You should exercise the usual caution and keep guard of your valuables especially around crowded places. In pubs and clubs better don't leave your belongings unattended." (wikitravel.org/en/Wrocław)
5. use that tool to calculate: numbeo.com/cost-of-living/comparison.jsp
One extra tip, if the company doesn't provide you any accommodation at the beginning, you can easily rent apartment through airbnb.com or 9flats.com online. Choose period of 1 month in order for prices to get little lower (some people give discounts for 1 month long renting). Usually you can rent short term apartment through these pages for only double price than normal market rental. It's still cheaper than hotel.
