Bettina's place is great. We were about 10 min ($9-$10 uber ride) from the Quarter. Rideshare services had no problem finding us. The house is close to a bus stop on the corner.
The futon is good for kids. It's thin and folds in the middle easily. The house is also close to a train, but it's not bad.
There's plenty of restaurants in The Bywater neighborhood as well.
I would definitely stay again, and would recommend it to others. Bettina was a great host!
