The place is a real gem. Try to get the penthouse as it has a really nice outside deck and lots of windows. We booked a lower unit and they had an opening and upgraded us at no charge. It was very easy to check-in and communicate with Stefan. They even provided us a complimentary dinner of tapas. It is now my go to place for Barcelona.
The only issue to be aware of is that it can be noisy at night as you are directly overlooking las Rambas, but that is also a positive as you are embedded in the nightlife. Enjoy.
