Hotel Catalunya was a great stay, had very nice rooms and friendly staff. The hotel breakfast buffet was a great spread, had lots of options and the view from the skybar was fantastic.
However, the air conditioning system in the room is horrible. The hotel sets the ac to automatically turn off at 24 degrees celsius with no way to over run it, so I found myself awake in the middle of the night sweating non stop. They sent a staff member up to fix the problem and he confirmed that the ac would not go below 24, so the rooms are basically always hot with no way to control the temperature. This was extremely frustrating. Further, don’t bother using the wifi as it is borderline useless. It would disconnect after using it for 2 minutes and you constantly had to keep signing back in. The wifi connection is also really really slow.
All in all, the hotel was very good and new. However, I would not stay again due to the room temperature situation.
