We had a great time staying at Julian's place. Although we didn't end up meeting, Julian was in constant communication from the start and provided excellent tips on restaurants and bars, a lot of which we frequented during our short stay.
The place was clean with a super comfy bed and had all the amenities we needed (coffee, fridge etc). There are train tracks nearby so do make sure you use the ear plugs Julian kindly provided if you are a light sleeper!
The location was perfect, although not immediately walkable we could get a 5 minute uber to the main part of east Nashville and we rented bikes on from then on.
Overall experience with Julian was great and I would highly recommend his place to anyone.
