ROOM SIZE WAS GOOD,A LITTLE BIT DISAPPOINTED ON THE VARIETY OF CHOICE FOR BREAKFAST .PRETTY MUCH THE SAME EVERY DAY...
A SHUTTLE GOING TO THE BEACH-CHAIRS AND PARASOL WOULD HAVE BEEN A PLUS AND A BETTER VARIETY FOR BREAKFAST.

It was nice to have a family room to keep the kids together close to us and at the same time giving us our own space
What I missed from the room was having a table with chairs

This hotel was brilliant for a short stay in Barcelona! The bed was a brilliant size, our view of the Tower & plaza was lovely and it’s in a great location - easy getting to the beach, bus stops nearby, plenty of shops and food options. The rooftop pool was also a great feature. Really enjoyed our stay here, thanks again!
No complaints other than some ants in the hallway outside our room but cleaners regularly worked to resolve this.

Good location, easy to get to main areas by a short cab ride
The rooms looked clean initially however our first room had black mould/damp around the window which the third single bed was placed by. The reception staff were kind and offered us a different room, I would recommend checking for own health reasons. The second room was okay however still was not clean for a 4* hotel standard, the bathtub had a ring of dirt/dead skin from when it was last used, we did not feel comfortable to use the shower/had to use sandals in the bathtub when a shower was needed because it didn’t feel clean. Overall ok however not 4*, could be great with improved maintenance
