We abosolutely loved staying at Aga's place. Location is close to Las ramblas and Gothic quarter and all other attractions are just a train away. Apartment was very clean and thanks to Aga we were able to put our luggage before our checkin time and even after our checkin time because we had a late night flight. She responded immediately for all queries and the instructions were pretty clear on how to get to the apartment.
Hopefully we will come back soon to barcelona. :-)
