All reservations require a valid credit card. A pre-payment of one night is charged to the credit card provided at the time of booking to guarantee and confirm your reservation. If the card is declined we will notify you as soon as possible to provide a valid card. We cannot guarantee availability until the deposit is processed. The credit card used at the time of booking is kept on file until arrival. The name on the credit card must match the name on the reservation, and must be the name of the guest staying at the property. Pre-arrival check in is required with government issued ID and customer photo. Unless other arrangements are made, Clarendon Square will authorize and re-validate the card on file for the full balance due on the reservation plus $300 for incidentals on the arrival date or up to two days before. If you have provided a Debit card, your bank will withdraw money from your account that will be unavailable to you for up to 10 days. We recommend that you use a credit card for securing your booking.


We try our best to accommodate every reservation while maintaining the boutique quality of our inn. In order to offer a personal guest experience, we give first priority to guests booking longer stays. For this reason, there may be minimum stay requirements set for your reservation. This may affect your ability to cancel and shorten your stay.
