I spent 6 nights in Acta Atrium Palace with my SO. We arrived in the middle of the night, but were welcomed by a very friendly staff that checked us in, in seconds. The rooms are of decent size, with comfortable beds, showers and everything you need. The room was absolutely spotless when we arrived and even though we left the hotel late for our daily escapades our room was always cleaned upon return. The swimming pool is rather small, but works wonders. The spa area (jacuzzi, sauna) in general was very nice. The hotel is located in the Gran Via les Corts, a rather busy and well known street. It's about 25 minutes walk from Barceloneta (the beach) and 10 minutes from Barri Gothic. It's 5 minutes away from the metro, making it easy to travel anywhere. It was a very pleasant stay in a very pleasant hotel. I'd vouch for it anytime.
