All the ones in Norway (Western fjord area) I stayed in were great, especially in Bergen city (the one in Bryggen) and Eidsfjord (at the end of a beautiful fjord). The one at Bergen airport (walk to the terminal) was a bit wierd, but otherwise great for a night-before-the-flight stay.
However, be aware that Norway can be expensive for food, so picnic creatively or starve or budget for that.

Especially in the countryside, but I found it a better experience to stay in the countryside -- in this case Eidsfjord -- for at least part of the stay than only to be based in the city the whole time.
And for 16K points a night (for hotels that cost $200++ in money), you can't beat the value.
(But you do have to get there!)
Choice Scandinavia is a slightly different hotel family than Choice elsewhere, but you can redeem there. But "slightly different" means "higher quality" (on a more consistent basis), which is very good IMHO!
There are decent Choice properties in London, but nothing that special, just a decent-enough property for a redemtion stay in that city where all hotels tend to have smaller rooms. (I couldn't find one at a great redemption rate and with a great location, though, that gave
both free breakfast and free interent -- just one or the other.)
In my US travels, I've mostly stayed in Choice hotels in conjunction with National Park visits. They were fine for that (a base for sleeping, when I spending most of my time out in parks anyway), but nothing to write home about as hotels proper. These were at the northern end of Skyline Drive (Front Royal VA), nortthern entrance of Olympia Nat'l Park (Port Angeles WA), main entrance to Zion and main entrance to Arches/Canyonlands (different parts of UT), etc.
