The first two nights we didn't notice the odor (we had noticed it the last time we stayed). Like I said, the first couple nights, no odor, the third day when we came back, it smelled like a sewer issue in the hallway and in our room. I used my Lysol which I learned from the last stay I needed. Other than this and the heating system, it was ok. The heater/cooler was either HOT or cold, no in between. It could use an updated heating system.
