Canopy by Hilton is a great place to stay close to NJ Exchange Place if you plan to visit NYC using the public transport system. Although they don't have parking space, you can park your car right across the street at the Morgan at Provost Square. The price is about $30 per night. Also, you need to walk about 12 mins to reach the Path station.
The room price was reasonable compared to other hotels in the area. The rooms were great coupled with modern amenities. The service was also great. We had an issue with the heating system, they sent a space heater right away. Although they do not have any studio style room where you may have your kitchen with a microwave. In fact, they don't provide any microwave at all. So, if you just plan to eat outside, this is the place you are looking for.
