Behold, the most expensive hotel suite in Washington, D.C. At $18,500 a night, this suite totals 4,000-square-feet with the added bonus of a 1,000-square-foot outdoor terrace with a firepit. While the suite is listed online with one bedroom and one-and-a-half bathrooms, the corridor is customizable to the point where you can add five additional bedrooms to your stay. One of the most unique features is that the corridor to the suite has closed caption security cameras. It is also the only suite in Washington, D.C. that is equipped with bullet-resistant windows, according to Director of Public Relations of the Four Seasons Hotel Liliana Baldassar. While the Royal Suite is not allowed for parties or cocktail receptions, the suite does come with a closed off area for an office and a room that can function as both a dining room and a business meeting area. For those who hate to walk through the lobby of the hotel, the suite offers a private entrance from M Street NW. Despite the Four Seasons Hotel opening in Washington, D.C. in 1979, the Royal Suite was not added until 2009. The space that the suite is located in was formerly leased for office space and was designed by Principal of Anderson Miller Ltd. Pamela Anderson.

You might fall so hard from house love that you'll consider disowning your own home—for a hotel room, no less.
