For any Ukrainian HN-ers reading this or for people in here who have relatives/close persons in Ukraine who want to escape the incoming war, for Romania there is this Facebook group [1] where there's a "matching" between what the people in here (in Romania) can offer, like accommodation or transport, and what the people escaping the war in Ukraine might need. The discussions in there are generally in Romanian and/or English, but as far as I could tell there was a decent amount of (Romanian) people offering accommodation to Ukrainian refugees. Sorry for the FB link but that's one of the few such things available right now.
Also, I can personally offer transport with my personal car (meaning 3 extra adults or 2 adults and 2 kids) from anywhere on the Ukrainian-Romanian border to anywhere else in Romania, if any of the HN-ers in here has someone close/a relative who needs that kind of transport inside Romania then leave a reply to this comment and we'll see about making contact/getting in touch.
