Blake's house is the perfect place for a large group of people--there are so many beds and the kitchen/living room area are really wide open, which is perfect if you're cooking together or lounging on the couch. The decorations are exactly as they are in the photos; we couldn't believe that there were signed guitars just hanging on the walls from country stars! (Admittedly I don't know them since I am not a country fan). The kitchen has everything you need to cook: lots of big bowls for serving, glasses for beer and wine, a massive fridge, coffee machine. We wanted to use the grill on the deck but it was pouring out the day we wanted to use it. There are two full bathrooms and a half bath, so there's enough space for everybody to do their business.
The house is just a 10 minute Uber/Lyft ride to downtown and there are two supermarkets just a 3 minute ride away. We didn't have a rental car, but it was still very convenient. Admittedly some of our drivers warned us not to go to the gas station a few blocks away or walk around outside, but the neighborhood seemed OK (we're not from Nashville).
If I had another large group going to Nashville, I would definitely consider staying at Blake's house again.
