Our stay was beautiful. The area is safe and quiet, there are some local activities you can do (hiking or kayaking is a possibility). Princeton is not a metropolis, therefore don't expect to meet many people around. To visit the center of the town.
The room was clean and full of optionals, including sofa, TV, desk, dish towels and soap.
The only CON is about washing machines and dryers. There are many on the 3rd floor but require coins, and unfortunately the reception is not able to give you cashback from credit card. I went to a gas station nearby and I paid $3 fee per transaction.
For the rest, there are nice restaurants nearby. The mexican restaurant next to is recommended
