From Prague Main Train Station (Hlavní Nádraží), take metro line C, one stop to "Muzeum".

There take line A for two stops to "Staroměstská".

Then it is just a short walk to our apartment block.

This is the recommended taxi transfer.

AAA taxi rank is located on “Wilsonova” street right in front of the main building of the Prague Main Railway Station at the right hand side near the exit from the building and operates non-stop 24 hours a day. Taxi rank is marked by the Prague City Hall as TAXI FAIR PLACE.

Prices and more info here.

The apartment block is located in a pedestrian zone, so cars are banned.
Ask the driver to drop you off at the junction of "Linhartská" and "U Radnice".
From there it is just 100 meters.
