on check-in, 1st room cleaning was not done completely, some used tooth brushes and pastes left in shower booth. I got a 2nd room where drain was not good, used water left in the floor of shower booth and leaked to toilet room from shower booth and bad moldy smell. After one night, I asked for a 3rd room of which conditons were better than 1st and 2nd and I stayed well there for the remaining 3 nights. In general I feel Novotel Silom needs to check all the room conditons and take some actions.
