Glyfada is one of the loveliest beaches on the island, in one of the loveliest settings. It is also one of the busiest at peak times because of this. You must take care in the sea because of the currents. Don't let that put you off, we go there frequently with our children and you should always keep an eye on youngsters in water anyway. There is a flag system in operation so you will know which days are more hazardous, but always err onthe side of caution. The beach is patrolled, at least during high season, by lifeguards. There are sunbeds for hire and some pedaloes/boats. If you don't want to use the sunbeds don't sit too close as we were once told to move away from them - I didn't think we were that close!
The resort itself is nothing more than a couple of hotels and a small holiday complex with the usual facilities. There are a one or two supermarkets, often some stalls set up along the road to the beach selling jewellery and such things. You will also find a couple of beach-side snackbars/restaurants. Glyfada is situated at the bottom of a fairly winding but not scary road, it is very wide and people often walk up ordown. At the top is the lovely village of Pelekas with splendid views, lots of places to eat and a few more shops.
If anyone drives down to Glyfada, during the high season you will have to pay for parking. I think it was 2 euros last time we were there.
It is a lovely place for a holiday and Louis Hotels tend to be reliably good.
Hope this helps,
