I've stayed at Pension Bahia 2 times now. The best thing by far is the location. It's located on the first street on the left as you walk down Las Ramblas from Plaza Catalunya and it's only about a 5 min walk from the Aerobus pickup in Plaza Catalunya. The most annoying thing is that it's on the 4th floor with no elevator, so be ready to carry all your bags up 4 flights of stairs! Besides that, the rooms are decent. The rooms/hallways/bathrooms look old and don't have a very nice ambiance, but everything is clean. Your in Barcelona, so you better not be spending much time in the hostel anyways, right?? For the location and price, this hostel is a great deal. Just don't expect to be wowed by the nice appearance of the rooms, hallways, and bathrooms.
