Location! Location! Location!
Close to Plaça de Catalunya, (which is a major hub; the double decker buses start here). Also next door to La Rambla, the quaint streets of the Gothic quarter, great restaurants and night life. The room is also nicely appointed - comfortable beds, blackout shades, very nice bathroom, ample storage space, safe. No USB ports, so make sure to bring plugs and converters.
The breakfast is good - buffet style with lots of variety (meats, cheeses, eggs, cereal) and they make-to-order anything additional.
When I make it back to Barcelona (I loved it here), I’d definitely stay here again!
