This is probably the best private room in home experience you’ll find in the area. The bed is huge and the bathroom is even bigger. Better than any you’d find in a hotel. The only caveats are that you have to be okay with quiet time after 10pm as there other guests staying as well. But even that was not much of an issue in the privacy of your room. We didn’t get the chance to interact with Rosemary as much as we were out all day. We did feel that we were given more than enough privacy and distance. Regarding parking, just be sure to communicate well and often and everything will go smoothly.
All in all, don’t be afraid to rent the room just because it’s in a home shared with others. It was much better than staying in a hotel.
