The apartment and the hand over of the keys worked fine. When contacting Aga for something, you get a swift reply. The apartment is fine if you don't mind walking up 3 floors of stairs and don't have a high standard. Having air-condition in the apartment is worth gold and helped us have comfortable sleep nights. The location offers many stores and restaurants around and you can get to La Rambla walking in 20 min. Shorter if you take the tram or bus which are just around the corner.
One huge pain was that internet was not working the whole time I was there and this was very important for me as I was in Barcelona for business. I contacted Aga about this multiple times which always was received with a reply. I was told the internet provider has been contacted and they promised they would fix the problem. Unfortunately, this never got fixed during my stay (4 days) and I ended up needing to pay for extra data volume from my cell phone service provider to be able to have internet. If I wouldn't of needed internet, the stay would of been ok but as I needed it for work things, unacceptable that I book an Airbnb where it's being offered but not provided. Before a guest arrives at the airbnb, this is something that should be checked prior from the host, not found out from the guest.
