Friends and I enjoyed our stay at Tony's and Katherine's place for a weekend. As others have noted, the home was clean, beds and linens very comfortable, bathroom was nice, and our hosts were quick to respond to any questions (and also checked in on us to make sure all was going well!) The welcome bottle of wine was much appreciated. Sharing the following with other potential guests in case helpful:
1) You don't need a rental car, but will take lots of Ubers/Lyfts to music venues, sights in town, etc. Fortunately, they come to this address quickly!
2) Neighborhood is lovely and quiet, but outside noise seems to carry (maybe from 12South area?), and historic bungalow floor boards are charmingly creaky, so if you are a super light sleeper, you'll want to bring ear plugs.
3) Home basics you would expect are provided (dish & dishwasher soap, hand soap, shampoo, etc.) For others, intro amounts are provided but you will likely need more during your stay or want to bring with you (toilet paper, paper towels, Keurig coffee & tea bags). Some items you will want to bring if they apply to you (conditioner, Kleenex). Without a car, we struggled to find drug stores in Nashville but were able to find toilet paper and Kleenex at the White Bison that has a small convenience store section on 12th Ave South.
We had a great time in Nashville and Tony's & Katherine's home made for a nice home base. Hope you enjoy your trip as well!
