What guests think
At Hotel 6400, travellers describe a clean, simple, self-service stay on the quiet edge of Sønderborg, with easy code-based check-in, free coffee and parking, and basic rooms whose bed comfort and amenities vary.
Some report missing access codes, no onsite staff, limited TV channels, and occasional noise from school groups or creaky floors. Breakfast feedback is mixed, with notes about stale bread, weak drinks, limited variety or replenishment, and timing constraints. Expect a no-frills base outside the centre.

Service
Code-based, self-service check-in is convenient for many, and phone support resolves issues quickly when codes are missing. However, multiple guests report the absence of onsite staff and that you clear your own breakfast table.
