Had a great stay in this part of Nashville and would definitely recommend. The room was slightly larger and better than I thought, and it was really nice to have the lounge area as well, although there is no window there. It was useful to have the kettle and coffee machine and fridge, we didn't use the microwave. The house is old, so the bathroom is perhaps smaller / older than the average American bathroom and some of the windows jam a bit - to be expected and part of the charm (and nothing unusual for Europeans!) There weren't any other people in the other room and I think the space and sharing the bathroom/toilet would have felt cramped if there had been. We found it all pretty comfortable.
The area is full of (mainly wooden) houses of different shapes and sizes, and its really interesting to walk around. Around 7 minutes walk gets you to the Five points area, which is definitely worth the visit if you have the time. We found more interesting stuff here than in some other areas, although you need to poke around a bit as it's not a big shopping area (thank goodness!) The 5 Spot was great for music, with a nice bar and simple food. We also enjoyed a (smokey!) 3 Crow Bar, visited Fanny's (music stuff) etc. So stuff to see and do. We also ate at the Treehouse for somewhat pricey, although very good, meal. We tried the Barista Parlor which is cool but not necessarily worth going out of ones way for.
Although there is a bus, it is a bit of a walk away so count an additional $15-$25 dollars a day for an Uber/Lyft. We did some Pool Ubers/Lyft and they were cheaper and not much longer and often no other person was picked up.
One thing I might do if I stayed again would be to head up to the Aldi / Kroger up Gallatin Avenue and get some yoghurt and fresh fruit, tea of choice and cereal. Probably we were out of luck but the shops nearby didn't sell such stuff and we found it hard to see a supermarket downtown Nashville. The recommended cafes tended to be in the direction opposite to downtown Nashville.
We only met Amy on the last day, but she was always quick to respond to any texts and was very solicitous as I wasn't feeling very well on the last day. She also allowed us to leave our bags until we needed to go to the airport, always something to consider with Airbnbs! Thanks Amy for a lovely stay!
