Most houses don’t have separate thermostats in each room, so this is definitely a problem you could run into. The last thing you’d want is for your guests to be drenched in sweat while your room is cool and comfortable. Here are some tips to deal with this issue: -Sleep in the room to see if it is comfortable- do this before you ever host, so you can figure out what your guest might experience. -Tell your guests ahead of time the thermostat is shared, and then allow your guests access to it if they’re ever uncomfortable. If you’re concerned about high electricity bills, give your guest a range to stay inside (let’s say 65-70 degrees- you can decide which range fits best for your home). Or, give them free rein to change the temp to whatever they want. -If you’re uncomfortable with your guests having access to your thermostat, you could always be clear in the listing that you control the temperature, and let them know about your typical temperature range. You could also provide your guest with a ceiling or box fan. -Another option is to place a heater in each room that you rent so that your guest can control the room’s temperature during those winter months.
