Nice design hotel at the Plaza Espanya. Great connections by walking, Metro and Train. The hotel has a very distinct design feel to it. Some of the design choices are nice, but there are few details that work less well. For example, shower/toilet is basically a glass box within the room and there are no curtains to block the view between room and shower. Depending on your taste, you might find this refreshingly exciting or slightly odd.
Overall the hotel has a great location, excellent pool and nice feeling.
