We usually stay at the Embassy Suites near the airport when in town. For an all-suites property, this is one of my favorites in terms of the layout of the suites and it's a relatively new property. It's also convenient to Easton Town Centre.
IIRC re the beds: they're comparable to what you'll find at most updated Hilton or Marriott properties (IMO). As noted above, what you're asking is very subjective and what is comfortable to one person, may be horrible for another so I'll hold off on further comparisons.
