We were 4 as family with 2 adults and 2 teenagers. This place has great view of the sea. We didn't need AC. Open the windows for a very nice sea breeze.
You definitely need a car - smaller the car better off. There is nothing walkable to eat. But the port is about 10min. Tons of restaurants nearby. This place is close by to north beaches. But south beaches are max 20min drive. Grocery stores are within 3min drive in either direction opening 8:00am-10:00pm. There is no washer but a laundermat is nearby. You surely need a road map and if possible GPS/google map. This Place we felt very safe even coming back at late night.
Overall we had a great stay. Don't forget to go to Pallonia to eat.
