Le Club Accorhotels - Sofitel Lafayette Washington DC?

This hotel apparently has just been on business for about three years and reviews are not plenty. Has anybody had the chance to stay or check out this property yet? Any input about the hotel's accomodations and dining services (Cafe 15)? I'll really appreciate it. Thanks! :)

I have stayed at this property once. I believe it was previously the French Embassy and was the site where the US accepted the gift of the Statue of Liberty. Rooms were stylish in a European way, the bar was pleasant and room service was fantastic (didn't eat at the restaurant)!

French Embassy?
The Embassy has been in Georgetown for several decades now.
I have not stayed there. But as far as I know, this was an old office building on 15th and H which was recently renovated and converted to a hotel.
