As Canadians travelling to Greece for the second time, we were aware that drainage issues are common. However, the Hera hotel seems to be impacted a little more than other places we have stayed, at least on one end of the hotel. Management would do well to instruct guests to avoid having a bath, as it leads to significant flooding. It clearly wasn't the first time as the floor had noticeable water damage outside of the bathroom and into the hall carpet. After our room flooded (bathroom and bedroom) we asked and were given a new room (on another floor), and noticed the same water stains on the carpet at the same end of the hall. If you have short hair and only take showers then you shouldn't have an issue, but with longer hair, there was soap and water bubbling out of the drain on the bathroom floor every time I showered. Other than that it was a lovely hotel; nicely decorated rooms, polite staff, and good location.
