The hotel offers a 24 hour shuttle service to & from the airport which is great. My room was spacious , my bed comfortable and the bathroom had great shower pressure. The bistro style restaurant has delicious burgers with sweet potato fries.
The extra star is a thank you to the staff for being so friendly and courteous. Even through Hurricane Sandy with no lights, no hot water, they did their all to make us feel as comfortable and at home as they could given their limited resources of a couple of generators and no power.
Go Team Holiday Inn Newark Airport!

We stayed at the hotel as we were on an early flight out of Newark airport the following morning.

The hotel was modern and clean and only 10 minutes drive from arrivals and departures. The room was spacious as you would expect with a Holiday Inn and the free WiFi was an unexpected bonus. The reception staff were helpful with guidance on the best way to travel to Manhattan.

We used the hotel shuttle bus to transfer to the hotel. You do this by taking the Airtrain to P4 (parking) and there are phones to call the hotel on the ground floor.

To get to Manhattan you can take the shuttle back to the airport, then transfer to the Airtrain to go to the NJ Transit railway station. The train takes 30 minutes to get to Penn Station in Manhattan. An alternative is to get the Newark Airport Express bus ($28) return to the Port Authority Bus Terminal (PABT) on West 42nd Street.

Overall a good hotel near the airport, which means you can also get into Manhattan should your time permit.

Stayed in this hotel for 2 nights as part of a tour organised by tours4fun in association with Supervacations. Barring the girl in the reception who didnt care who walked in or out, and was rude when I asked her if she has an adaptor as I come from India, my phone was dead. I had nothing to complain about. The rooms was spacious, clean, with a tea and coffee maker, a large tv, radio and alarm, clean toilets, room was cleaned daily. There was free wifi in the room which was a big relief. Only thing odd was that the sink was outside the bath room, literally in the bed room, and it woke up my wife when I went to brush my teeth. This is the first time I have come across a room like that, Though the hotel was next to the highway and near the airport, I never heard a thing. All in all, a very comfortable stay and would be happy to recommend this hotel to anyone wanting to stay. Food in the restaurant was pretty expensive, never tried, and there is nothing around, so carry some snacks with you.

Needed a hotel room on very short notice close to Newark airport. I booked this one based on a good experience at another Holiday inn. Would definitely stay there again. The hotel was very clean and the staff very friendly. The bed wasn't great, but it was good enough.
