Beautiful property, plagued by service issues
My husband and I stayed at the TaiPan floor for three nights. Overall, we love the location of the property and the view of Jefferson Memorial from our window. The room is well appointed with adequate amenity. However, we found the service rendered left much more to be desired. The best experience was with the wonderful person at the Taipan Club (didnt get her name though remembered that she is likely from East Europe) as she was pleasant and extremely professional and attentive. My husband said that the rest of the time the Club was staffed with far less finessed staff and he was shocked at their unprofessionalism (loud conversaitons amongst themselves, loud laughters, all but reflecting the quality of the brand). We had issue with one room service where we ordered salad as a side choice for main course, but french fries arrived. When I called down, the person interrupted me and read my order back to me. There was nothing wrong with the order. They simply delivered the wrong item and if only she had a bit more patience to let me tell her why I called. When we checked out, we were told by the reception desk that system was down and that they took my email info and would email me in a couple of hours. That email never came, so day later, I had to call. When I finally received the bill and reviewed the bill, internet charges appeared which should have been waived for Tai Pan club guests. 
Nothing all that serious in and of itself, but a string of them are decent enough of sample size to reflect some of the service issues there. I had better experience at Omni DC or Park Hyatt DC.
