Hotel is located in Zone 2 of Barcelona rail system, so one need to pay extra ticket to travel back and forth; it takes ~15 min to walk to the station, 5~10 min to wait for the train and ~30 min to travel to Pl. Catalunya - overall 1h to get to Barcelona in each direction.
Hotel is very simplistic, room has minimal comfort, simple bad with simple mattress - not comforting your back. Breakfast is just bread and cheese ham jamon, no single piece of vegetable or even eggs. WiFi works and gives at least one of the package promises.
Bottom line: for that price B&B in Barcelona is much better deal.
