Overall this is a good place to stay and a reasonable price for what it is close to. There are a few issues I ran into but these may not bother others and as they say ymmv.
PROS:
Check-in was extremely easy and the building is very secure, requiring different codes for entering the building, accessing your floor, and your room. The area also seems safe and a friend who lives in Newark also confirmed this as he knows the area.
I didn’t have many questions for Yuki but he did respond very promptly and had check-in info to me well ahead of my arrival.
Newark-Penn station is only about a 10 minute walk away. There is quite a few homeless people hanging around the block of the station but I was never really harassed. Note: Bello’s is right across from the station and I recommend checking it out. Huge beer selection and good food.
There are a lot of excellent places to go to eat in the area for all meals and several convenience stores. Be sure and go to Brasilia which is right on the other side of the block.
Having access to a full size fridge and kitchen area is very convenient. We didn’t use it but others staying there did and cooked dinner.
CONS:
The beds are not the most comfortable and a little short. My friend is 6’1” and his feet were almost hanging over the edge.
During our stay there were issues with the water pressure. It would randomly disappear for a few minutes while trying to shower or clean up in the sink; sometimes to the point where there was only a trickle coming out of the shower head. It always came back after just a few minutes and didn’t happen every time but it was slightly annoying.
If you need windows to be completely blacked out to sleep you may have some trouble as there is only a shade and the room gets brighter when the sun comes up.
Tl;dr: Beds and water pressure weren’t the best. It’s in a great location, is safe and secure, and has excellent choice of food and quick access to public transportation.
