Great location, very central, clean comfortable rooms and beds. Tea and coffee-making facilities on the first floor were certainly a nice start to our day.
One male reception staff member was most helpful, accommodating and apologetic about our prior request for a quiet room when booking our four night stay. As this hotel is located above an underground train path, my light-sleeping travelling companion experienced insomnia for three of our four nights stay and was only able to get a good nights rest when we were finally relocated to a room on the fifth floor. I, on the other hand, slept very well after lots of fresh air and long walks around Barcelona.
It would be nice to return to One Shot Arago 257 again in the near future.
