There aren't that many reviews around for Husa Arenas Hotel so I'll hopefully add a bit more information. I definitely recommend this hotel. Very friendly staff and the room were always kept clean and tidy by the cleaners. We didn't get the double bed we requested, but the single beds were bigger than what we were used to, so there was no problem. The location is great. I couldn't find any directions on the net, but there is a train stop, on the L3 (green) line called Maria Christen which is just down the road, a 3 minute walk. And that line takes you into Barcelona centre in 15 minutes. It's spot on. The price was ok, but be aware you have to pay extra for breakfast, something which I forgot so I was surprised when I received a nice bill on my way out. Breakfast was self-service and 10 Euros a head. I would stay there again :)
