How to reach us
We can be reached by subway through Subway Line 6, Republica Argentina, and Nuevos Ministerios (Lines 6, 8 and 10) as depicted on the map. In addition there are bus lines coming and going to Sol and Callao.
From the airport
Barajas airport has four terminals. As described in the homepage of the airport, all terminals are conveniently connected to the subway Line 8, which ends up in Nuevos Ministerios, close to the institute. Alternatively, you can also take a train line that stops at Nuevos Ministerios and has a slightly lower frequency.
Another alternative to reach us from outside Madrid is to take a taxi. While it has a flat fare of 30 euros, it is still more expensive than public transport and it can be a rather long trip depending on the terminal and on the traffic conditions.
Public transport tickets
Tickets are valid for both subway and bus and can be purchased at the machines and ticket counters in the subway. The price varies between 1.5 euro for a one-way ticket and around 12 euros for a ten-trip ticket, but you have to pay a supplement of 3 euros when travelling to and from the airport.
Please note that you have to stamp the ticket prior to entering the subway or the bus, and that a single stamp allows you for only one trip -- unlike in other places, every time you switch means of transport you have to purchase or stamp your ticket again. If you take more than five means of transport a day, you should consider buying a tourist ticket valid from one to seven days and unlimited travel.
