First of all, Katie is by far the best Airbnb host we've worked with. She's super responsive (often within minutes) and provided a lot of helpful information, including travel tips for out-of-town guests.
The condo itself is very cute and very clean. The kitchen is fully stocked, Katie even had coffee for guests. I couldn't have been more pleased with the hospitality.
Location wise: It was very enjoyable to stay right on the Cumberland River. The condo felt so cozy and had a great view. As others have noted, it's about 15 minutes to walk right into the downtown area, or a $5 Uber/Lyft. I will say that the walk itself isn't great - we didn't have any problems, but after one day realized that at night time/in the dark, it was more comfortable to just Uber home.
In summary, we're very thankful to Katie and would definitely recommend this Airbnb!
