I host rooms in my home, and I live here too. I specialize in long terms and the rents are cheap and cheerful. Common area cleaning up after one's self is right in the rules. It's little things that take seconds, like taking shoes off, spraying the shower after use, putting the seat down, and covering food in their suites or if they use the kitchen. Easy.
Each room has its own mini fridge, microwave, coffee pot, kettle, etc. BUT I do NOT allow use of the oven or stove (actually my home insurer doesn't). This cuts the noise, mess, and bs in half. There are plenty of tasty and inexpensive eateries nearby, and I also cook a couple of times a week and invite them for a bite as a gesture of goodwill. They can also use the dishwasher and the onsite laundry. I also invest 2-4 hours a day in common area maintenance, but yeah, some of that mess is mine!
A typical guest is a resident MD on roationstaying a month or more. My standards have to be exceptionally high. During a changeout, we literally rip the room and bath apart with a checklist. Bedding, feather duvet and cover, towels, pillows, flooring, appliances, etc are all sterilized and scrutinized or immediately replaced. Windows are cleaned, curtains washed, floors polished, touch up paint applied; drawers sprayed, a couple of fresh flowers, a chocolate, and snacks etrc. are added. I usually have another pair of eyes proof the room for anything I've missed. Only when it is 100% will this poor man's Leona Helmsley with sign the welcome note.
My rates are low, but my cleaning fee is on the high side because it's a more accurate reflection of what is involved.
