My experience is that you have read the listing extremely carefully trying to devise what is it about.

Is it a whole flat, or a room in a property with the landlord living in, or a room in a property fulled rented on airbnb (how many people?), or a bed in a bunk of beds (yes that's a thing). There's listings for everything and quite a few are misleading. It doesn't help that you have no idea what is the normal price range when traveling abroad and may not speak the language very well.

If you're interested by the way. My counter experience renting a flat on airbnb over the summer, is that guests are evaluating everything they could use including beds and couches and ground space. The guest renting a one bedroom could be anything from a person or a couple to a family (maybe with extended family/cousins joining in) to a group of many friends. It's always a surprise whether there will be 1 or 6 people showing up.
