The Airbnb is attached to the owner's house. You have to go through the back to get to the "bungalow" separate part of the house. We accidentally tried to go through the front door the first time, but Ben, the host, is super nice and welcoming.
The host offers coffee, lots of towels, and plenty of dishes/silverware. The Airbnb fits 4 people comfortably and the host is very nicely decorated. The Airbnb is also in a very central location. We took Ubers everywhere we went (downtown, Broadway, Vanderbuilt area, etc) and it costs about $8 for the Uber one-way.
The only minimal downside is that the owners live upstairs so you'll hear some foot-steps/noises but they try to stay quiet until about 9:00 AM as noted in the description. So just a warning if you're looking to sleep in past 9:00 AM. Otherwise, I wasn't bothered by any noise.
Ben, the host, is very nice and welcoming. He cant be contacted via text/phone call and is very accommodating when we needed something.
I would definitely stay here if we visit Nashville again.
