We were so lucky to find this gem and hope to be able to stay again next time we're in Barcelona.
The apartment is stylish, clean, and perfectly located for anything you are doing. La rambla de catalunya is full of shopping, art and architecture, there are hundreds of restaurants throughout the neighborhood, and the metro stop ("diagonal") is just a block away.
I also wanted to make a point to mention the staff, as they were wonderful. From check-in, to the front desk at the office, to the cleaning ladies, everyone was friendly, helpful, and went out of their way to make our stay wonderful.
