My spouse and I have stayed at this hotel 6 times in the last 4 months.I am a retired travel consultant and have stayed at Marriott properties several times and this hotel is by far my favorite.
It is basically a business travelers hotel,during the week the rates are $200.00 and higher but on the weekends can start around $109.00 per night.Parking can be extra,wifi can be extra so check online or with a res agent when you are getting rates.And do not be too proud to actually call their toll free number,through 25 yrs I have rated Marriott reservations dept number one,they will get you the best rate curtailed to your needs
The rooms are super clean,my only complaint is the bathrooms are super small,hardly room for two unless one is in the shower!The staff is amazing,Joseph at the bell desk,all the front desk and super cool Colin,concierge staff and just everybody! Nice bar(check for Happy Hour),it has a huge amazing patio,breakfast buffet is great in their restaurant.
Want to see DC? The White Flint metro is a very short walk and will take you (with a change of trains)right to the Smithsonian Mall. Lots of families staying there during the summer when we were there.
