We ended up with Unit 408 because we had so many issues with the previous room, right across at Unit 407.
I cannot recommend 407 at all, it seemed it was never cleaned. When we first arrived, it had such a strong odor of cigarette smoke. This caused me and my spouse to have horrible health issues due to the smoke. Eventually through long waiting (took 20 days) & poor communication, we were finally moved to 408.
Pros of 408 are a comfy bed and location is close to public transit.
Cons were neighbors next door smoked marijuana daily with their door open. The weed smell came into our room. The heater constantly blew out. Over 8 times in one day. I had to ignite pilot light myself. Be warned, there's bugs! Small cockroaches, we had to be careful of our luggage and not take the critters with us. I killed over 15, rest were too fast. We had to wash all the dishes before using them, same for drying rack. Wine glasses still had wine stains. There's cigarette burns on the white coffee table.
