The Sagittarius Apartments are rented privately which means a package where your flight is arranged for you is not possible.
The best way to organize your holiday is to firstly contact the owners of the apartments to make a provisional booking, then to secure your desired flight and finally, after your flight has been confirmed as a secure booking, to confirm your apartment.
Flights to Kos can be booked through a variety of ways including internet sites eg., www.lastminute.com, www.ownersdirect.co.uk., http://www.thomsonfly.com/., www.flythomascook.com/.
Your local travel agent can also help to find a flight. Bear in mind that you only need to be sure to arrive at Kos Island airport so it’s possible to book a very inexpensive package to either Kalymnos or Nissyros islands which have to use Kos airport as they have no airport.
