Dormy Inn Ikebukuro Natural Hot Spring

This is my second time staying at Dormy Inn, and the hot springs, ramen, Yakult, and ice cream are still available. However, the service is truly disappointing. Since my check-in day happened to be my birthday, I emailed the hotel to inquire about a possible room upgrade, but received no response. When I asked about the unanswered email during check-in, the first English-speaking staff member seemed dismissive. Then, a Chinese-speaking receptionist told me that even for a birthday, they only offer a small card and nothing else. Alright, I guess I had high hopes. They directly gave me a corner room where the window opened up to a wall. I stayed for four nights. On the morning of the third day, I explicitly requested housekeeping, but when I returned, only the towels had been replaced; even the trash can wasn't emptied. Because I used a Trip.com voucher, the price was discounted. If this is why the service was poor, I hope the platform and the hotel can communicate better. If they can't handle promotions, they shouldn't offer them. Am I being discriminated against for using a voucher, or is it because I'm Chinese? The breakfast was overpriced and low quality. When I asked a staff member if they had wasabi, they said no. Can you believe that? In the room, you can't even tell if it's sunny or rainy outside. Judge for yourself.
