We recently stayed at the Samaria Rooms and had a really bad experience.
While making our reservation we specifically asked for a Double Room for a couple, with a double bed, when we arrived they showed us a very small room with two single beds. The owner refused to accept this fact and basically forced us to take the room for one night even though we wanted to leave. The air conditioning unit made noises like it was about to explode and during the night it also started pouring water into the room.
It goes without saying that we left the place a day later and moved to a nice little studio in Frangokastello (10mins drive from Chora Sfakia). Much better than Chora if you ask me, and a huge beach strip in which you can always find a little privacy.
I would stay away from Samaria Rooms under any circumstances as they are dishonest.
