The apartment is indeed 20m from the sea, and only 15 minute walk from the centre of the village. You can walk along a rocky path on the shore (not suitable for everyone) or via the road. We would walk into the village bakery in the morning and bring back fresh-out-of-the-oven bread for breakfast.
The apartment is airy and has ample space for a family of 4. The shared pool is a good size.
The host, Ntina, was very friendly and eager to make sure that we had everything we needed. She brought a new set of pots and pans, which we never used - there are plenty of great (and cheap) Tavernas in the village.
The village itself is lovely. Not too commercialised and not too quiet. All the locals are friendly. If you want more life, a bus runs into Rethmyon every half hour €2.60 each way.
Unless you are looking for a club scene, Panormos is perfect!
