The Songbird House is a spacious old home on Music Row that has been subdivided into many (5 or 6?) small apartments. Our large group of 10 friends stayed in 3 of them (#1, #3 & #4, I believe). The location is close to Vanderbilt & Belmont university and a cute little shopping district with restaurants and a bottle shop (though the grocery is most most of a mile away). A Lyft to downtown was always at the ready and less than $10.
The apartments are tastefully and charmingly done up with vintage style and modern kitchen and bath fixtures. Everything is accurately pictured. Many niceties are provided, like snacks and coffee, first quality linens, and kitchen and bath supplies. More or less everything we every we opened a cupboard or drawer hoping to find was thoughtfully provided. Jill also offers lots of her own local recommendations for food and entertainment which helped us get oriented and find a few good meals.
During our stay, the house contained a mix of AirBnB units interleaved with permanent residents. Every unit is self contained with its own nifty electronic locks, but you should definitely plan on running into neighbors in the shared entryways, and you should plan on them hearing you and you hearing them move about as you come and go up the wooden stairs and across the charming wood floors. This probably wasn't the ideal set up for our big group of vacationing friends arriving home well after the bedtime of neighbors who have to work in the morning, but if late hours aren't part of your Nashville agenda, the Songbird House is a great find.
