We loved our stay at Richard's. It is close to some great breakfast options and also close enough to Vanderbilt University if you want to wander through there. Richard had great tips and advice to offer us, and was also just a genuinely interesting person!
You do have to walk through his front room to get up to the room, so it's best if you are comfortable with that. It's also a bit of a trek downtown, but cost about $10 using Uber/Lyft so very easy to get there and back. Would definitely recommend his place if you want a quiet spot to explore Nashville from!
