Things we really appreciated:
The location right near the subway station, right off of Broadway -- great;
How clean the apartment was,
Decor - great eclectic mix of old and new and funky -- it's clear he is an interesting person and really cares about the place;
The many thriving plants;
The coffee and tea set up;
How responsive he was - especially when the wifi briefly was down;
The laminated information sheet;
The roof access;
The bathrobes - we didn't use them but it was a nice touch.
