How many people can stay in a villa booked ?

Villas typically limit occupancy to double occupancy per bedroom, allowing only 2 guests per bedroom. While it may be feasible to include one additional guest beyond the listed maximum occupancy, approval from the owner is an obligation. Additional guests may incur charges for an extra rollaway bed and/or surcharge. Each property has its own set of regulations and requirements.
Please be aware that infants and children are counted as guests and should be included in the total party size. It is important not to assume that children are exempt from the guest count when making reservations.

What is the minimum stay in a villa ?

Usually, villas require guests to stay for a minimum of 5 to 7 nights. This is due to the extensive time, costs and resources needed to prepare the property for the next guest, a process that differs significantly from hotels. Consequently, villas necessitate longer stays compared to hotels.
During the Christmas and holiday seasons, villas may enforce a minimum stay requirement of up to 14 nights.
Occasionally, properties may consider waiving the minimum night stay requirement if your travel dates are within 45 days or fit into an availability gap.
Please do not hesitate to contact our reservation team if you have any questions.

Can I wash my clothes at the villa ?

Each of our villas is equipped with a washing machine, and the majority also feature a dryer. However, these appliances are primarily designated for use by the housekeeper for household laundry tasks, with a few exceptions. Notably, villas in St. Barts typically do not provide accessible washers or dryers.
Access to these appliances is generally restricted due to liability concerns and insurance policies. Misuse of the washing machine and dryer can result in flooding and other liabilities, hence the restriction is in place for the mutual benefit of our guests and villa owners.
Recognizing the importance of having laundry facilities available during your vacation to lessen packing burdens, the housekeepers are typically willing to assist with your laundry needs for a nominal additional fee, which can be arranged during your stay at the villa. We also recommend reaching out to your concierge to inquire about the possibility of accessing these facilities.
