First of all, let me say that this place is in a fantastic location. Located on a quiet street but within walking distance to Plaka and the Acropolis. Check-in was easy once you find the place. The private rooftop was a HUGE plus!
My biggest complaint is that while the living space and main bedroom are gorgeously appointed, the 2nd bedroom is TINY and depressing. While the main bedroom is spacious, well-decorated, has full length mirrors, plenty of storage, etc., the 2nd bedroom is the size of a postage stamp. This wouldn't be so bad if the walls weren't completely bare and there was no room to put any of your stuff. My friend was living in luxury while I felt like I was living in a jail cell.
If you're going with enough people to have to use both bedrooms, someone's gonna end up being REALLY unhappy and jealous of whoever gets the main room.
