We had an absolutely wonderful weeklong stay at Fox Cross Cottage. The property was immaculately clean, cozy, quiet, and restful. We stayed 7 nights. We went into DC a couple of days, then visited numerous Civil War sights/battlefields the rest of the week. We loved the surrounding countryside. We drove 4 days off of the main thoroughfares so we could immerse ourself in the area while reaching each destination.
As for the cottage, the beds were comfortable, the furniture was plenty and comfortable, and the location was fantastic. We didn't have time for any homecooked meals or outside grilling, so I can't comment on any of those things, but the kitchen was very well-stocked with everything I could think of needing.
Lastly, working with the owners was a fabulous, relaxing process. We simply couldn't have asked for better hosts. All in all, I can't recommend this property enough for a small group. Granted, it sleeps 8 total, but that would have felt a bit cramped to me. I personally think it's best for a group of 6 or less, but everyone is different.
