Finally, a hotel with enough power sockets, and in the second building at the back it was very quiet. However, this depends on the neighbors, as the walls are not that thick. Otherwise, a very comfortable bed, enough space, also a seat in the form of an armchair, the TV also showed foreign programs. The safe was big enough for a laptop and camera. I would suggest they would provide memory foam cushions - as the soft ones are sometimes bad for your back.
The indoor rooms are a little unfavourable as far as the weather is concerned. As the windows only face the atrium, you don't know whether it's raining or storming outside. But this is quite normal in many apartment blocks in Barcelona, so it's not a problem.
I found the staff to be very friendly and courteous. And I look forward to staying at the hotel again. Maybe then in a room with a view - even if it's at the back so it's quiet.
