We had been looking at a Baltic cruise for a few years and this one had a reasonable price. We'd always sailed on mid-size ships (1000-2000 passengers), so we had a bit of concern about a big ship, but new experiences is what travel is all about, right?
We were in a mid-ship balcony on the 11th deck.

Close quarters, but well laid out and plenty of storage if you know where to look.
