Comfy bed for better sleep

A cozy, modern suite with its own private entrance. A set of stairs leads to your covered deck and step into your own peaceful retreat — living area, kitchenette, private bedroom, and 3/4 bath (no tub). Smart TV, WiFi, and central Heat & Air included. Minutes from Historic St. Charles, the Katy Trail, and St. Louis.

We do not have auto-book, so, please watch messages for a pre-approval note and respond to that.

The space
The Castle Kearan Guest House is a modern, private retreat tucked behind our ranch-style home. Step through the sliding glass door and into a clean cozy contemporary living space that feels like a home, not a hotel.
The kitchenette is well-equipped for easy living — mini fridge, microwave, hotplate, toaster, toaster oven, and a Keurig coffee maker as well as a regular auto drip coffee maker. A water dispenser keeps you hydrated and has both cold and hot water. The bathroom sink does double duty as the kitchen sink, for cleaning dishes in between meals. With a little creativity, you can cook pretty much anything.
The private bedroom offers a restful night's sleep, in a queen sized adjustable base bed. The 3/4 bathroom (shower/no tub) is clean and well-stocked. High-speed WiFi, a Smart TV with Roku, and central Heat & Air keep you comfortable year-round.
The covered deck has a fire table & a tapestry with a scenic landscape of a castle in Scottish Highlands. One of the best features — perfect for morning coffee or evening wind-down. It's your space, enjoy it.
You're minutes from great dining, Mid Rivers Mall, and easy highway access into downtown St. Louis. Historic Old Town St. Charles — with its charming Main Street, restaurants, and riverfront views — is just a short drive away. Several concert venues are also reasonably close.
Outdoor enthusiasts will love the proximity to the Katy Trail and Missouri's incredible trail systems.

Guest access
Your only shared space is the driveway and parking area. Please park past the white line, near the stairs. Everything else is yours.
Your private entrance is up a set of stairs to a covered deck and straight through the sliding glass door into your living space. You come and go completely on your own terms.
One thing worth knowing — the deck continues past the main house back door and connects to the backyard, which is the relief area for our Great Dane, Zara. There is a gate between our decks so she wont be a bother. One incredible rare trait she has is she does not bark. She's a sweetheart with people and will likely want to say hello, but she can be a little uncertain around other pets. If you're traveling with a service animal (no pets, please), just give us a heads up ahead of time.
