1. I don't want to stay in a hostel. See below for more on this; but, hostels, at least the ones I have researched, have bunk rooms and shared facilities. Hard pass for me.

2. I don't like sharing a bedroom and, especially, a bathroom in someone's home when they may be there. There's simply a different level of security (potentially false, I understand) in a hotel vs a rented room in a house.
