As described by Rick Steves, the hotel was well located on a quiet Plaka street. We walked everywhere. Our room was clean and well designed. Breakfast was delicious with lots of variety. Good chance to try Greek pies and sweets! Front desk help were very helpful.

The Hermes has a great location, within walking distance of the Plaka, the cathedral, Monastiraki Square, but the walls in the rooms are paper thin. You can hear conversations in the room next to yours. :( Not good.
We were traveling with family and the floor of the shower in their room was partially black-mold, mildew, just some sort of stain? We don't know what it was but-yuck. That room (Room 301) also had musical pipes-every time the water went on, the pipes banged and gurgled, loudly.
Good location though.
