Disorganized, they said they left the keys in one place, we got there, asked the lady (who did not spoke a word of English, only polish) she told us (by sign language) that there was no key there, we try to call the responsible person, does not answer. we call some polish friends, they answer the polish number but still no keys. We go to have dinner and start thinking about options (it was almost 2 a.m. and we had no where to go) the polish friends get a call, they go back and then there was a key.
After getting the key, we go to the address given, the key does not belong to that door, we try to see if there's a back door, still no door for the key. Then we notice the address on the key chain, we go there, does not work, back door and we can finally get in. We get in, settle up, look for the wi.fi, there is a wi.fi password, but no wi.fi network name. We try this long and complicated password in every network available, does not work in neither of them.
Conclusion, the house itself was ok, but this whole situation was really bad, and if we didn't knew someone there it would have been even worse.
