We had a good stay at Yuki's place. It was very clean, conveniently located and good value for the money. We had breakfast at Pao da Terra and dinner at Casa d'Paco, highly recommended!
It's a 10-12 mins walk to the train station where you can take the PATH train that takes you to World Trade Center in 22-24 mins during weekdays. During weekends, it takes a bit longer and it includes a nice ferry ride.
Something to note is the private bathroom for room 3 is not ensuite.
