Decent hotel, Perfect location.
The Carlye Suites has been my home away from home on dozens of occasions. 
I must say that the location cannot be beat! It is in the heart of the best neighborhood in Washington, and just a short walk from everything good about DC! 
Overall, the hotel is clean, but perhaps not as modern as major hotel brand. It's "ART DECO" from the lobby and common areas to the rooms. 
All rooms have refrigerators, and most have full kitchenette facilities! This is a GREAT thing to have for simple preparations-- however some guest ruin it by attempting to cook a steak dinner or a fry happy breakfast that permeates and lingers in the room for the next guest. 
Book away from rooms ending in 22,24,26,28.... they are cracker box small... and in the hallway that connects the two buildings. 
I don't think you will be disappointed in this hotel... they try! And will do their best to make you feel at home!
The internet-- while generally reliable-- is a pain because it signs you out every time you close your computer or your phone falls to sleep! But it's free!
