You absolutely do not want to stay here unless it is a last resort. It is great apartment in a great location but there are lots of similar apartments. The main problem is checkin. It is very inconvenient. The off site check in process added an hour to the check in compared to a normal airbnb rental where the owner meets you at the apartment. The need to drop off keys at the main office adds an additional half hour to check out.
You are MUCH better off spending some of the 90 minutes you would spend checking into and out of this apt instead finding a real airbnb rental from a normal owner who meets you st the apt.
Another issue is that unless you read carefully the listing can be misleading. It gives the impression that you are renting from a Eva and Jaques. In fact Apartment Barcelona is a large company. Correspondence is disingenuously made to look like like it is from the supposed hosts. It is even signed by Eva&Jaques, when in fact it is automated, automated upsale of add on services, or from company staff.
The reason this matters is two fold. First checking in and out with a centralized agency takes a lot of extra time. Second, this type of company is the target of demonstrations in Barcelona because they remove potential longterm local rental unventory, in favor of high priced tourists short term housing.
