Just got off the MSC Seaside.
We did 2 weeks (back to back)
And here is my honest opinion. If you don't like what I I write so be it.
Average but small bathroom and smallest shower ever seen at see. Noisy since I think there is service station right under used by the buffet employees. Also could hear the partys from the atrium when going to bed before the end. Very well located on the other hand.
