Carolina is an amazing host. The carriage house is close to lots of public transportation. It is also an easy 20 minute walk to the U.S. Capitol. The space is great for 2-3 adults and makes great use of the available space.
We had a great stay. We travel with an infant and Carolina had a pack-n-play, high chair and baby gate waiting for us when we arrived. She also provided us with some basic groceries since our train arrived two hours late.
