I am going to Barcelona soon and I have a question regarding public transport in Barcelona. We will arrive at the airport at 11 p.m. and have to go to this address afterwards: Sancho de Ávila, 22, Sant Martí Barcelona, 08018 Is it possible at that time of day to go there with reasonable comfort (i.e. no changing 5 times) and in a reasonable time frame by public transport or would we need to take a taxi? I haven't found a public transport site for Barcelona yet or at least nothing I could work with. so any help is greatly appreciated. And if you have any other tips about what to see other than the obvious tourist sites - I am happy for any tips!
