There are loads of places to stay in Clifden, for the back packer there is hostel's in the village to campsites. There are cheapish B&B's and not so cheap B&B's. There is some hotels and the a great one right by the sea. But while in Clifden during the summer I would recommend that you go camping and really take in the surrounding. We couldn't find a actual campsite but we did camp near a lush beach and its was so worth it.
