It's the second time we've stayed in this hotel and it was just as good as last time. They are super welcoming, available by text and very accomodating (they arranged a transfer from Piraeus port to the hotel for us). The hotel is very nice, clean, quiet, and the room is spacious.
It's a 5-10min walk to the subway (Omonia), and 20min walk to the Acropolis. We love the neighbourhood of Exarchia, there is a lot of nice restaurants, coffees and bars, and it attracts much less tourists. We recommand this place !
