As someone who lives in the States and has stayed in more than one Homewood Suites (though not the one under discussion), I can verify that the chain as a whole lives up to the high standards already reported. These are new properties with rooms that are very well furnished. Only disadvantage is that the price is sometimes high for the number of beds you get, since rooms are so well furnished. But if you are looking for a hotel something like the DVC timeshares only more reasonably priced, Homewood Suites is a great option.
The 3-star vs 4-star raring should not be taken as a measure of quality; it's more a measure of the level of service provided. Since Homewood Suites do not (as far as I know) offer room service, valet parking, actual in-hotel dining, etc, they get a 3-star rating.
