For me, it depends on the natural light in the room. What the woodtones of the furniture are and what colors you hope to use with it. Kind of Doctors office color but it's a personal decision.

A lovely color for a bedroom but I use bedding to start color scheme for bedrooms and for sure with a guest room. Sorry not many reviews on paint colors usually but if you like it and it works with the bedding do it and stop analyzing . And if you want real help we would need to see the space and the bedding.

I don’t think someone’s experience will help, as there are too many factors to consider. The articles below may help (2nd has a visualizer), but your best bet is to get a test pot. If you already have bedding, art, accessories and furniture, consider getting a quart to get a feel of the outcome. If you’d like recommendations to complement what you have, provide some pictures.
