Marcellas airstream is a truly lovely place to stay! The airstream is designed with great attention to detail, it is very cute and very cozy! I loved being surrounded by animals, it feels like you are taking a break from the big city. The location worked great for us, close to great food and drink spots, we did rent a car though.
The only tough part for us was not having a regular standing shower (bathtub only) since we came for ACL and wanted to clean up after the festival each day. However, the bathtub is a vintage clawfoot tub that is absolutely gorgeous and was SPARKLING CLEAN!
