All international flights arrive at Václav Havel Airport Prague. You can take:

a) Public transport 

Find your transport connection using IDOS, or install the IDOS application.
Go to Connections, select 'Praha + PID', either use 'My location' or 'Letiště Praha Terminál 1' or 'Terminál 2', and as your destination, check for the nearest bus/tram/metro stop to your accommodation.

You can also use DPP, and search for your connection from 'Airport (Terminál 1)' or 'Airport (Terminál 2)' to your accommodation.

There are bus stops located just in front of the Arrivals building. You need to buy tickets in the yellow machines (press full price: 30 min / 30 CZK or 90 min / 40 CZK or 24 h / 120 CZK). After you get on a bus, you need to validate the ticket. Tickets are valid for any means of transport (bus/tram/metro/train) in Prague for the selected time. Without the validation, your ticket is invalid, and the passenger is treated as if he had no ticket.

The Honest guide video can be helpful.
