Hi,
Sorry I can't really help. However, I am also researching this hotel for 2008! We stayed at the Golden Sun Hotel, which is right next door to the Louros last summer. We can only go for a week next summer so wanted to return to a resort we know and like. I've read quite a few hotel reviews on tripadvisor and all are very good.
The hotel is a few minutes walk to the beach, and around 10 minutes walk to the main Kalamaki road with plenty of restaurants and bars to choose from. We particularly liked this location as we tend to spend the days on the beach, also we could walk to Laganas along the beach if we wanted to dive.
I too would be interested to hear if anybody has stayed at the Louros.
