Have anyone stayed in hotel Regina in Barcelona?

I know there are many discussions on this topic. I booked hotel Regina per people's recommendations, but now I am looking more closer to all the hotels and it looks like Meridian, Purlitzer or 1898 could be nicer. Any ideas / suggestions? My issue is that I booked using my airline points and in order to switch, I need to cancel and rebook, but I don't want to do it before I know the availability and how many points I need to spend. Can anyone comment on hotel Regina please? I am also curious if they have King size beds.

I am also curious if they have King size beds.

If you check the website, you will see that they offer either Queen size beds or two twins:

I stayed in this hotel a few years ago. It is very nice.

It was quite nice three years ago.
