Not only are "red pillow" Ibises a wise, if not only, choice in many locations - especially if it is just a stop on your way - but they tend to offer good breakfasts and overall aren't that bad if what you want to enjoy is the location, not the hotel. "Green pillow" Ibis Styles take it to the next level, with many blowing competing higher-brand hotels out of the water with comfort, design and location.

As said, this all depends o nthe property - there are run down Ibises you wouldn't want to stay at unless you are looking for a "scary hotel" experience (sometimes cheaper than Disney's Haunted House), but just as well there are Mercures, Novotels, Sofitels et al. not worth staying at, even if you pay with points (i.e. stay partially for free).
