We stayed here during Christmas and our room was on the ground floor. The interior of the hotel was very nicely decorated, our room was big, bathroom was small but clean and manageable, and the TV had a few English channels (one with movies) which was a bonus.
One con was that the staff were not very friendly and always unsmiling. When we asked for some help to find our way to Delphi the manager seemed quite frustrated and snapped at us for asking her questions, so we were wary afterwards to ask too many questions. Additionally, our room's toilet was leaking but the manager didn't provide us with much assistance until we complained a few times, and another staff member offered us a different room. The manager herself didn't actually attempt to help us out at all.
Free wi-fi; breakfast was ok but not great; location was 5 min walk from Acropolis and entrance to old city.
In summary, very pretty interiors, worthy of the boutique title, but unfriendly staff which can damper your stay.
