Our normal check in time is 4 pm, and check out time 12 noon. A four hour window between guests is fairly standard, and absolutely necessary in order to prepare the cottage for the next guest, as we want to make sure it is spotless. Tammie chose to arrive later, and leave earlier, which is of course her prerogative.
The cottage does share a backyard, and we always make a concerted effort not to disturb our guests. However, we did not know exactly when she would arrive, and happened to be in the yard when she did.
The price per night is perfectly in line with the pricing of similar lodgings in the area. Tammie originally booked for just herself (at a lower rate), and then unexpectedly showed up with a friend, resulting in a higher rate.
