We chose this cruise primarily for visa free Russia and the lovely city of St Petersburg - the other 13 ports were a bonus, but although we had been to all the countries before, we did get off at every one.
First thing to note is that Stockholm hotels are expensive as are drinks in Swedish bars - save money at the 7/11 :) Plenty to see in this capital, but get to the Vasa museum very early or leave it late to avoid all the cruise parties. Easy to get to port on public transport, although we used an u ber for about a tenner from city center.
Embarkation was a breeze and we were on board very quickly - note, do not queue outside if you already have your luggage labelled - just drop it off. We went straight to our room to drop our hand luggage and use safe and headed to the bar as room was still being made up. I think we were on board for 1pm. We asked to get our bed split too to make our inside cabin more functional - have no idea how 4 people will survive in it, but was fine for 2.
Two cases fitted easily under one bed, plenty of hangers available, with adequate shelving and drawers. Small TV which we only used to watch the bow camera, lighting slightly dark, fixtures slightly rattly and walls thin. Noise was not really an issue and ear plugs blocked most noise. Bathroom was fine if a bit old and only complaint was shower drained slow, very slow. No windows made it easy to sleep as was pitch black, but hard to know what was going on in the morning. Also no phone signal in cabin :(
