I have two rooms that are occassionally listed for airbnb guests. There is one bathroom between the two rooms - a door goes to each room. The house was build in 1908 so there are skelton key locks on the doors and it's an older house with original door frames and doors that I don't want to damage.
Initially there was a lock on the inside of one of the doors so that someone from room B wouldn't walk into the bathroom if it was in use. However I found that the guests in room A were locking and not UNlocking it - so then the B room guests could not access the bathroom at all. The lock could only be unlocked from the inside, so someone would have had to go through guest room A into the bathroom to unlock it.
Because this happen both times we had both rooms booked, I disabled the lock.
I left a skeleton key in the door so that Room B could lock the bathroom door so that guests could not go INTO their room...
But now I'm left with the fact that when someone is in the bathroom they can not lock the doors to prevent someone from walking in on them. I feel like it isn't a major issue as you can clearly see light coming from under the door when you're in either of the bedrooms, however I have had guests comment on it privately.
I can't think of a way to hang a sign or something when it's in use, as that would require guests to open the door to the other room....
Ideas? (for a second as I was typing this I was thinking maybe a laminated card that they can slide under the door into the bedroom saying it's in use, and then they pull it back into the bathroom before they leave?)
