We stayed at the Maritime for 3 nights pre-cruise.
The good: Location and breakfast included.
The Not so good: The room is so small we had to stack our suitcase in a corner and could barely walk around the bed because of it. We are used to small European room, but this one was smaller than most.
The Bad: The smell, we had to keep our bathroom door room closed at all time, as the smell of the water was awful. I'm not saying it's the fault of the hotel, but we dreaded going to the washroom because of the smell. We noticed the same smell when doing a boat canal tour, so I suspect the water may contain sulfur or something.
Copenhagen was a nice city, but EXTREMELY expensive, so make the most of the included breakfast! We spend 3 days there pre-cruise and that was too long, if we were to do it again we would only spend 1 day there.
We took the train and the subway to get to the cruise ship and it was fairly easy. They had an elevator from the surface to the trains, so no problems with luggage. The trickiest part is getting the tickets, try to have enough changes, there is no attendants, machine only :(
I we were to return to Copenhagen we would definitely try a different hotel, but most probably in the same neighborhood.
