Had a great stay at Tiffany's place on our first trip to Nashville. The location is perfect, you are walking distance to everything in downtown Nashville--great restaurants, bars, museums, shops, even the arena where we saw a concert (there is a nice pedestrian bridge from downtown across the water). It was so convenient to get out of the concert and not have to deal with traffic and fighting your way out of the parking lot. You could just stroll the mile back to your lodging.
There is a great brewery a few blocks away from the lodging (Tennessee Brew Works) which had a wonderful selection of beer and good food. Even though the downtown area is half a mile away and very loud and crazy, at Tiffany's, it was surprisingly quiet. Unit had two nice bedrooms with fully stocked bathrooms, a large open living room/dining area/kitchen, with a balcony. The pool is shallow but nice for lounging about. There is a little workout room too. Tiffany was very helpful and easy to communicate with. Plenty of parking at the building. Unit has everything you will need.
Once you arrive, you really didn't need a car although since we had one, we did explore some great neighborhoods like the 12 South area (near the I Believe in Nashville mural). We will definitely stay here again, met our needs perfectly!
