Fifteenth-century castles aren't known for their hospitality.

For starters, there's no indoor plumbing or climate control. The on-site food options are suspect at best. And you simply cannot discount the possibility of a dragon attack. 

Though if you're staying in a new Rosewood hotel that just so happens to be housed inside a completely renovated 15th-century castle, we like your chances. 

You'll find Rosewood Schloss Fuschl in the Austrian Alps, where it's surrounded by mountains and forests and situated on the banks of a picturesque lake. That puts it conveniently between a couple of UNESCO World Heritage Sites: Salzburg and Hallstatt.

The castle dates back to 1461, when it served as a hunting lodge and summer residence for the Archbishop of Salzburg. It's been many things over the past few centuries, and most recently a hotel. Rosewood rehabbed the entire space, so it's now sporting 98 luxury guestrooms, including 42 suites and six chalets. Those rooms feature residential amenities, like sofas, desks, marble baths and rain showers.

There are several top-notch dining venues on site, so you can mix things up throughout your stay. Schloss Restaurant is your all-day option, serving regional cuisine and wines. Seeterrasse offers global cuisine with views of Lake Fuschl. And Vinothek is a casual wine bar and wirsthaus-style lodge with a selection of classic Austrian dishes.

The hotel is also home to Rosewood's Asaya spa concept. The holistic wellness spot features a heated outdoor infinity pool, an indoor pool, treatment rooms and a fitness center.

When you're not ensconced in a robe or headfirst in some schnitzel, your location gives you access to all-season activities. Summer on Lake Fuschl means time on the water or hiking through the surrounding mountains. During winter, the resort transforms into a snowy wonderland, where Alpine adventures during the day lead to cozy evenings by the fireplace at night.

And probably some cozy whiskeys, too.
