Haffro is a chill dude!
The place is easily recognizable and quite clean and good. I arrived quite late in New York, and was worried I may not be able to spot the place. Fortunately, it was easy to find.
Haffros instructions on checking in were also very clear.
I'd certainly recommend staying over. The penthouse is quite large and you end up meeting different people in different rooms as those are on Airbnb too, so it ends up being a fun interaction.
