How to get there
FROM BARCELONA AIRPORT, EL PRAT
Take the aerobus and get off at Gran Via/ Urgell and the hostel is just 5 min. away from there. Ask for Casanova st and find number 52. You can also take the train to Plaça Catalunya and then walk to the hostel (20 min.) or change to line 1 (red) and get off at Urgell. It will take you about 1 hour total. You can also get off from the train at Passeig de Gracia, take line 2 (purple) and get off at Universitat. The hostel is just 5 min away from there on foot.
Taxi: If you decide to take a taxi from Barcelona El Prat to the hostel it will cost about 30€.
If you are flying with Ryan Air pay attention on the airport you are arriving at: Barcelona El Prat or Girona (the one in Girona is 1hour and 15 min. away from Barcelona by bus)
FROM GIRONA AIRPORT
You'll have to take a bus that will take you to Barcelona. That will take you 1 hour and 15 min. and the bus will leave you in Estació del Nord. There you have to take the metro in Arc de Triomf, line 1 red, and get off at Urgell. It will take you 3 min. on foot.
FROM SANTS-ESTACIÓ (The main train station)
Take the underground line 3 (green) to 'Espanya' and there change to line 1 (red) to 'Urgell'. Go straight to Gran Via de les Corts Catalanes and turn left into Casanova, look for number 52. There are several exits, so the best would be to ask for the street once you are outside the underground.
If you are coming from any other place you must know that the nearest underground station is, appart from Urgell (line 1, red), Universitat (line 1, red and line 2, purple).
There are also buses but the underground is the fastest way to travel in Barcelona.
