Prior to my arrival the host sent a message with specific instructions about how to enter the house and the room. Unfortunately we didn't get to meet Michael, however he kept in touch. The rented room is separate and below the house level, which is pretty convenient as flights come in and out from the airport nearby.
Also, the room had a little pantry which turned out to be very convenient. However the bathroom wall don't go all the way to the roof, so that makes it a little less of a private place.
