Disappointing
We found our experience in this Hotel so disappointing and not what we expected of a Four Seasons. We have been lucky enough to stay in the Four Seasons Palm Beach, Las Vegas and Beverely Wilshire and found the service to be exceptional. Washington was nothing like this. 
Right from check in, our children weren't greeted with the lovely gifts or bath products or chocolates etc that the Four Seasons normally spoils them with. No-one asked if we were celebrating anything special. Our room which was a suite with an interconnecting room was very dated. The children's bathroom was so small only one person at a time could fit between the toilet and the shower. Our air-conditioner broke down as did our main TV. The maintenance crew were lovely though. There was food stains all over the remote control and the sofa. I had to wipe them down.
 Our experience in the Steak House dining room, included having to send back a burger because we found a hair baked into it. On a positive note the staff were very apologetic.
The Hotel tried to brighten up our stay by way of a discount yet this wasn't deducted at check-out and we had to ask for it. We were also overcharged by a substantial amount and only now a month after our stay have we received a credit. 
On the positive side, the Concierge was very helpful in sorting a tour for us. We appreciated this. We also had the occasional access to the house car which was also great as was the ice cream shop down the road from the hotel.
Overall, a bit of a disappointing introduction to Washington.
