The hotel was very modern, clean & close to many attractions in the area. The staff was very friendly & helpful. The parking garage needed repairs badly but everything else was amazing. I would definitely stay again when visiting DC.
Concierge staff were extremely helpful and genuinely friendly. The restaurant was amazing, excellent food and staff. The restaurant team made our family feel so welcomed.
This property has the friendliest and most attentive staff I have ever encountered at a property. It’s brand new and gorgeous. The design choices are bold and unique, but remain elegant and elevated. Large room sizes. Highly recommended.

The staff were friendly and helpful, and the hotel was clean, stylish, and well-run.
The hotel breakfast was SO good. The location is perfect for visiting the Hill. Our room overlooked an inside conference room and there was some light that came into the room at night. Played with the curtains a couple of times and got it to an acceptable level, but if you need complete dark ask for a different room.
This hotel is perfectly located if you're traveling by train or plan to spend time at any of the museums near the Capitol. The rooms are spacious and clean. The staff are lovely. It's steps away from Union Station and the Capitol, and very near many of the the Smithsonian museums. We didn't bring our dog this time, but we have in the past and it worked out great for us. I also used the fitness center and locker room while there. Oh and we ate dinner and breakfast in Bistro du Jour and food was delicious.
