patricia,
easyJet is my preferred budget airline in Europe and I fly with them whenever possible, which I did again in September on a flight from Porto to Basel. Once again the experience was very "easy" and pleasant. I should add however that lately I've been paying for Speedy Boarding and advance seat selection, which makes everything so much "easier". That provides a much faster trip through the bag drop and boarding, and allows me to get seated and get a space in the overhead bins before the "herd" arrives.
I'm not sure what type of reviews you were reading, but you may want to have a look at these.....

As with any budget airline, it's important to read the Terms & Conditions carefully, especially related to baggage rules. Passengers who just buy a basic seat are allowed ONE carry-on item. That doesn't mean "one plus a personal item", it means ONE only. Passengers who pay for some of the options I mentioned above are allowed a personal item. If you'll be checking baggage, pay attention to the weight. If the weight of your luggage will be over the allowable limit for the first tier, it's MUCH cheaper to pay for the next highest weight limit at the time of booking, rather than at the gate.
As others have mentioned, you can print out your boarding pass up to 30 days prior to the flight. If you check-in at the airport, there will be a charge for that. In some airports, passengers are bused out to the plane using the "kneeling buses" and boarding is via stairs at the front and rear. I find that quicker than using the sky bridge.
