We typically stay at the Sheraton when we visit Stockholm. The last few times opting to (gulp) stay with family instead. The Sheraton location was not great for us, bc we felt trapped in tourist land. The last time we were there about 2 years ago, we were upgraded to a large corner suite with a living room that could be locked off, which was perfect to have the family come visit. The Sheraton was fine, nothing overly special.
This year we are staying at the Nobis, mostly for location and to try something different. It's much more convenient to my in-laws and local cafes, shoppes, that we like to go to. Any other Plats stayed recently and have any stories of upgrades? We are going for Xmas and typically the Sheraton has been super dead in previous years, so I expect the same here.
