We’ve stayed here for about three of our visits to DC and we really do not prefer to stay anywhere else. The location is perfect and right by everything, the hotel is clean, the hotel staff is wonderful and the amenities are suitable. We really enjoy this hotel.
Phenomenal stay. Attentive staff, clean rooms, wonderful on-site restaurant and great location. Would absolutely recommend and will be returning myself in the future.
This hotel exceeded our expectations. The staff, especially Aleck (Mr. Virgin Island), who helped us check in, was extremely patient and accommodating. I highly recommend this hotel and plan to return!
FYI, I found my driver's license!!
We had a comfortable stay. A bit noisy at night but our bed was good and bathroom accessories met our needs.
The breakfast staff was slow and not engaged with our desire for coffee.
I prefer breakfast buffet included with our stay.
We splurged on our usual hotel budget and we're so glad we did. The hotel was lovely and the staff was wonderful...but most importantly, the ability to walk (quickly) to and from Union Station and to other points of interest (allowing us to have a car-free weekend) was our deciding factor. We weren't disappointed and would stay here again.
Very clean, nice large rooms and you can see the attention to detail everywhere you look. Comfortable beds, beautiful furnishings, classy but unique decor, and tons of small touches and helpful amenities that set this hotel apart. Plus, very reasonable prices for the level of hotel you're getting here. Will definitely stay here again!
Beautiful, comfortable hotel with huge rooms within easy walking distance to Union Station (Amtrak). Onsite restaurant with room service. Highly recommended.
Overall a very nice hotel. The staff are nice and professional. The property is maintained. My room was was clean enough, but the area behind the toilet lid had some brown grout and the shower had a few slightly brown stains. It can be a tad noisy from the guests.
This hotel was so lovely! Loved the 24/7 snack area, room service food was very tasty. Staff was very friendly and helpful. The room was quite cozy, pillows were the best hotel pillows and the fact they provided slippers in the room (rooms have hardwood floors) was a cherry on top. This will be my top pic when I come into the city.
I have stayed at this location several times. The lobby, common spaces and rooms are clean and airy. The staff is very friendly as well. If you want to be near Union Station or the Georgetown graduate/law schools, this is the best option.
Upcoming arrival the reception hall was inviting. Hotel staff pleasant and helpful.
Rooms clean and no odor.
Bathroom clean without mildew in shower.
Bed comfortable.
Room lights were unique and helped create a warm and restful ambiance.
Would stay again.
I loved the decor, the staff, the bed was so comfortable, the room was beautiful and I loved the French restaurant right at the hotel. All was perfect!
