Cabin 6103 is a handicapped cabin. To request this cabin type you must submit a letter from your doctor to Celebrity stating that you require the cabin for medical reasons.
The only way that Celebrity releases these cabins into general inventory is if they are close to the cruise date and don't need it for a specific request.
Handicapped cabins are wider than normal balcony cabins, with a much larger bathroom and roll-in shower. The bathroom is built to ADA standards.
The balcony is a bit wider, but not deeper.
