Hotels Lucerne Switzerland - side trip from Geneva

Hello Travellers! I’m visiting my best friend in Geneva for a couple of days and she suggested I also go for a couple of days to Lucerne to see a different part of Switzerland. Does anyone have ideas for a good hotel in Lucerne? Ideally something walkable from the train station since I’ll have my luggage. Any traveler have experience with a specific place they loved? I’m not looking for 5-star luxury, just clean and comfortable.
