I've been offered a council house which has old stone tiles all downstairs, hall, lounge, dining & kitchen. Will it be freezing? Will rugs keep it warm? Or should I go for carpet / laminate over the top? I could live with it in the hallway, easy to keep clean, but the lounge? I think it will be cold. I've got a few weeks to decorate before I move in but want to spend as little as possible. Any ideas?
