The staff in this small hotel is extremely helpful and generous with their time. The breakfast buffet is fresh, plentiful, and includes home-made specialties. They helped me arrange sailing and my ferry back to Athens. When the AC wasn't really putting out, a technician came immediately on a Saturday night to fix it. The only other drawback is that you must climb a short hill from the harbor, but the water view from your balcony will be worth it. Londos is a real find!
Also, Piso Livado is wonderfully quaint and quiet, but has also shops, restaurants along the harbor, and its own beach. If you want to avoid the crowds in Mykonos, Santorini and even Naoussa on Paros, this is the place for your vacation.
