From Barcelona Airport:
The best way is to take the "Cercanias" train C10 towards Barcelona, the third stop is Sants Station. It runs from 06:00 until 23:44 every half hour. For this journey you can already buy a ticket called T-10 (ten journeys) at the vending machines, this is also the best ticket for your travels in Barcelona.

The hostel is located five minutes walk from Sants Station, the main Barcelona Station where all trains and most national and international buses arrive.
There is also the Aerobus (blue) that goes from the Airport to Plaça Catalunya and Sants Station. This one takes a bit longer because it goes to the city center and back, and it?s more expensive.

Once at the Station: Get out of the Station by Plaza Joan Peiró (by the taxis), go straight through Passeig San Antoni, pass the cinema and take the 4th street on your right, it´s Galileo Street (by Boccatta Sandwich shop). Walk Galileo St and stop at the third street on the right, it?s Melcior de Palau. We are located at number 70-74, on top of the furniture shop!

From Girona Airport:

Take the Barcelona Bus outside the airport and stop at Barcelona Estació del Nord. (1 hrs)
There you?ll find metro L1 at Arc de Triumf, take it and stop at Plaça de Sants. (10 min)
Get out of the station and take Galileo Street (by Bocatta Sandwich Shop), keep walking and get to the third street on your right, its Melcior de Palau (5 min). We are on top of the furniture shop.

By train:

Most trains will arrive to Barcelona Sants, but due to extension works some international trains have been diverted to Estación de França.
If you are not lucky and arrive there, don´t panic, there is a new train service from França Station to Sants Station, is the service that covers the line Barcelona- Airport (C10) stopping at Sants Station. It runs from 5:12 to l 22:42 every half hour.
