Address: ELI-NP, Str. Reactorului 30, Magurele, Ilfov
IFIN-HH has two gates: main gate, which is right at the end of the Reactorului street, and the ELI-NP gate, which is at the end of a road on the right side of IFIN-HH. It is easier if you come to the ELI-NP gate because it is next to the conference center (otherwise you have to traverse the whole institute). Hence, in case you come with a taxi (or Uber/Bolt/etc) and the driver stops at the main gate (should not happen if you give the ELI-NP address, but rarely it does happen) tell him/her to continue a bit further.
