Q: We will be visiting Barcelona as a group. There will be 15 members in our party can you help us find accommodation for groups for our Barcelona visit?
A: For group accommodation we recommend an apartment rental instead of hotel accommodation. The reason is it is works out much cheaper and you have more of a natural environment with the other members of the group.
I recommend you first read a little more about apartment rentals in Barcelona as an option to hotels. We have written an number of informative articles.
