We had a great stay at Teo and Brian's house although we didn't spend much time there as we left early and came back late. Teo and Brian are are really nice and welcoming and always answered our messages within minutes. It's in a little distance to the train-stop Journal Square but there are at least a minimum of three different buslines going there frequently. From Journal Square you can take the PATH which goes to the WTC 24/7.
We would definitely come back and stay there again!
