I've stayed at the Golden Sun three times now and always been more then happy. Everyone who works there is always very friendly and helpful. Rooms are more than adequate and a good size. If i have any grumble, it's that the breakfast is not particularly good. Pretty sure they could do better with a little imagination.
Overall, though, well worth a stay at the hotel, and Glyfada itself offers lots of great shops and cool bars. |
