It was great living at Jennifer and Roland's place! They were easy to reach, answered questions quickly and made us feel welcome.
We had a minor "hick-up" upon arrival as the door code didn't work. But we were able to reach them literally within a couple of minutes and get the correct code. And then there were freshly baked buns on the kitchen counter waiting for is when we went in the apartment! What a nice gesture! The apartment was exactly as described, clean and welcoming, and there were towels and shampoo in the bathroom; as nice as in a hotel but with a personal touch.
The neighbourhood is really nice and arty, with a lot of restaurants and cafés within a walking distance. The little Italian café just around the corner is great (particularly if you like macchiato and other espresso-based beverages) and the Left bank burger restaurant within a 10-minutes walk is also tremendous. The communications are really good with two commuter train stations nearby. Something we hadn't considered from the beginning is that PATH (the commuter train that runs from Jersey to Manhattan) uses other tickets than the subway. That lead to a slightly higher travel expenses than we had reckoned with, but on the other hand we couldn't have found an apartment that good and for that price (even including the higher travel expenses) on Manhattan, so it was totally worth it.
All in all, if you are going to NY, make sure you stay at Jennifer and Roland's! We are totally doing it when going to NY again!
