I genuinely love that 'rent just a room' (or even just a bed!) function of Airbnb, and continue to use it till this day. Have met many interesting people (or as I heard another comment on here say "weird in a non-dangerous way" lol), and it's always felt like a safe and quality experience to me (so long as I always do the due diligence and use common sense to stay with hosts that have tons of positive reviews, etc). IIRC Airbnb had a push a few 'releases' ago to revive this core part of their founding purpose, but now it seems they've moved on to 'services'.
