Notes:

*The upper deck is currently unavailable due to ongoing renovations. The lower deck remains fully accessible, including the hot tub area for your enjoyment.

*This property is seasonally lakefront. Water levels on Island Park Reservoir fluctuate throughout the year. Typically, the water is highest in spring and early summer, and by late August the shoreline may recede. When water levels are up, guests can enjoy direct lake access and use the dock located right next to the cabin. When the water is lower, the dock may sit on dry ground, but the reservoir is still accessible nearby for boating, fishing, and swimming.

*WINTER: Roads are plowed but we HIGHLY recommend an AWD or 4WD vehicle during Fall, Winter and Spring months.

- Pet-Friendly Home: This home welcomes up to 2 dogs! If you plan to bring any type of pet other than a dog, or more than 2 dogs, please inquire with us prior to booking, as additional approval is required. Please note that not all types of pets can be accommodated.
Prime Properties Guest Rules & Stay Standards:
Our goal is to provide every guest with a clean, safe, comfortable, and accurately represented stay. These standards are intended to protect our guests, our property owners, our neighbors, and the homes entrusted to our care.
By booking and occupying the property, guests agree to follow the rules below, along with any property-specific requirements included in the listing or arrival information.

1. Arrival Inspection & Reporting Concerns
Please take a few minutes to look over the home when you arrive.
Any cleanliness concerns, existing damage, missing items, maintenance issues, or conditions that may affect your stay should be reported to Prime Properties within three (3) hours of check-in, preferably through our direct phone line and with photos when applicable.
This reporting window gives our team a reasonable opportunity to verify the condition and provide a timely solution during your stay. Concerns first reported substantially later in the reservation or after departure may be more difficult to verify and may limit the remedies we are able to offer.
Urgent safety, water, electrical, heating, access, or other significant issues should be reported immediately.

2. Smoking & Vaping
Smoking and vaping are not permitted inside the home, garage, or any other designated smoke-free area of the property.
Guests may be responsible for reasonable costs associated with smoke remediation, odor treatment, additional cleaning, damaged furnishings, or other restoration required as a result of smoking or vaping. Where permitted and properly disclosed, smoking-related remediation charges may begin at $200 and may increase based on the extent of the work required.

Guests remain responsible for damage caused by an animal to the same extent they would be responsible for other damage caused during the reservation.

4. Check-In & Check-Out Times
Please observe the check-in and checkout times listed with your reservation so our teams have adequate time to prepare the property between guests.
Early check-in or late checkout must be requested at least 24 hours in advance and is subject to availability. A fee may apply depending on the amount of additional time requested.

Unauthorized late departures that interfere with housekeeping or an incoming reservation may result in an additional charge, including up to $50 per hour where disclosed and permitted.

5. Registered Guests, Visitors & Events
The person named on the reservation must be part of the group staying at the property unless the booking platform allows otherwise or Prime Properties provides written approval in advance.
Only the number of overnight guests included on the reservation may occupy the property unless additional guests are approved.
Parties, events, receptions, or other gatherings exceeding the property`s approved occupancy are not permitted without prior written authorization.
The booking guest is responsible for the conduct of all members of their party and any approved visitors.

6. Cancellation & Date Changes
The cancellation policy shown on the listing at the time of booking applies to the reservation.
Requests to change reservation dates do not automatically override the cancellation terms associated with the original reservation.

Prime Properties provides a starter supply of common household items such as toilet paper, paper towels, soaps, trash bags, dishwashing products, and similar essentials.
These supplies are intended to help guests get started and are not necessarily stocked for the entire length of every reservation. Guests are responsible for purchasing additional consumable supplies if needed during their stay unless otherwise stated in the listing.

If you believe you left something behind, contact Guest Services as soon as possible. When an item can be located and returned, a $50 fee will apply and must be paid before shipment.
Items will generally be held for 14 days after checkout. Items not claimed within that period may be discarded or donated.

9. Damage, Missing Items & Excessive Cleaning
Please report accidental damage or broken items as soon as possible. Early communication often allows us to resolve an issue quickly and prevent further damage.
When practical, please leave damaged or broken items in a visible location rather than throwing them away.
Guests may be responsible for reasonable repair, replacement, specialized cleaning, or labor costs resulting from damage, missing property, misuse, or conditions beyond normal use of the home.
Charges will be supported by documentation when required by the booking platform.

10. Furniture & Property Setup
Please do not relocate furniture, mattresses, televisions, large décor, outdoor furnishings, or other substantial items without prior approval.
If furniture or other property is moved, it must be returned safely to its original location before checkout.
