We've stayed at this hotel several times and at many other Homewood Suites. The hotel is well run. Breakfast buffet is better than many other Homewood Suites. Rooms on high floors toward the back are very quiet.
It's a short walk to the Metro and easy to get into DC. If you don't want to walk, the hotel has a free shuttle to the Metro and other nearby places. Many restaurants are within walking distance.
Only negatives are that the rooms are smaller than at other Homewood Suites and computers in the business center are slow..
