This includes the total of any estimated taxes paid by the travel service provider (such as a hotel company) at the time of your booking and/or by us to tax authorities (including but not limited to sales tax, occupancy tax and value added tax). This amount may also include hotel fees, cleaning fees and other fees paid to and/or retained by us, the hotel supplier and/or the website through which you booked, our work and/or services on the site. Please see terms and conditions for more information.

The crossed out online rate shown is the lowest public rate we found for the same room and stay dates on leading travel sites.

Expedia Group verifies all reviews to ensure that the customer has indeed booked on our site. To encourage customers to submit their reviews, we send an email containing a link to evaluate the hotel to which we sometimes attach a reduction or Expedia Rewards voucher to use on a future trip. We post all reviews whether they are positive or negative, to the extent that they respect our content directives. This monitoring is automated. Any rejection is manually checked and, if maintained, notified to the reviewer by email with reasons. We do not otherwise process changes, nor reviewer contact. We de-list reviews after 4 years, other than for properties having a non-significant number of reviews.
