This actual house was fine, but we would not return. For starters, the rental is the guesthouse with the owners living about 50 yards away and they feel highly empowered to just pop over whenever they feel like it, without wearing masks, and banging on the door repeatedly until answered.
We initially thought they were just being nice and friendly, but it turns out they were being nosey. My wife and I had originally rented the house just the two of us for New Years and a few days before decided to bring a second couple along who had their plans fall through; there are two bedrooms as well as an upstairs with twin beds so we didn't think it would be an issue having 4 people in the house. Well, the owners made sure to go out of their way to report that we had additional people staying so we received an unexpected $240 fee subsequent to leaving.
Additionally, Fredericksburg is a relatively small town so during on a cold rainy day during COVID, there isnt much to do. This is probably on us for not verifying, but the house does not have wifi or tv so something to keep in mind for when the weather is poor.
Finally, if you do decide to bring additional people such that you will need to use the beds upstairs, please be aware that the temperature up there is about 15-20 warmer than the rest of the house so sleeping upstairs would probably be relatively unpleasant.
