I had stayed at the Hyatt Crystal City for Conference for 5 nights and they could not accomodate us but the Renaissance could for one more night. That night was great. The staff was very friendly and accomodating. The room was impeccably clean. The lobby has a boutique hotel feel to it, something I am not accustomed to with the Marriott chain. It reminded me of a Klimpton, or W more than a Marriott property. The coffee bar / cafe Illy (yes the European Coffee) was great. Had good service, great coffee, good selection, everything fresh and appealing and tasty. The restaraunt in the Hotel we only ate the breakfast but the staff was very friendly, and helpful and the food was hot (something it was not the 2 prior mornings at the Hyatt Crystal City across the street.) This is a great hotel. Wonderful stay.
