We stayed for three nights in Pauline's Airbnb because we needed some days off beetween our work. The room was really big, comfortable, clean and the kitchen was good equipted.
But I think it is not okay to go in someones guestroom without asking (we were not around) to close the shutter, curtains and turn off the heater, while valuables and all of our stuff was in the room.
This might be well-meant, but not the kind of privacy some guests are looking for.
