I stayed at The Quisby for my solo trip. I really liked the hostel as it had breakfast every morning. It was clean and had a separate floor for females only. they have a very cool bar and also offer free drinks sometimes. This place is very close to the French Quarter. It is easy to get around the city from where it is located. Also for the swamp tour and plantation tour, there is a pick up from the hostel.
I had a chance to meet some very cool solo travelers and exchange stories. I am glad I made reservation with them, I will be more than happy to stay here if I go back again!
