I avoid booking reservations that leave 1 or 2 night gaps on my calendar. I must book my guests back to back, or leave at least 3 nights between reservations.
If your requested dates leave a 1 or 2 night gap with an existing reservation, I will not be able to accept your reservation.
More details: I do not allow online booking. To book, contact me with dates and occupancy info. A $250 refundable deposit is required to book, and prompts me to block the calendar and email a contract. I don't ask for any portion of rent upfront. Rent is due one month prior to your arrival. If it helps you to make payments along the way, that is perfectly fine. The $250 deposit is returned promptly upon a tidy check-out. I take e-check for payment which processes for free. Credit cards cost 5% extra.
