We stayed at Aga's place for 3 nights and we were delighted with her hospitality. Aga was super friendly to us from the very beginning. She sent us a detailed instructions, how to get her place and was waiting for us when we arrived.
The apartment is in a great location, just few steps from the metro station, or 10 min walk to the city center. It has been just reconstructed, so everything is new, clean and fresh. There is a balcony in the room with a view on the main street behind the corner. There were completely no collisions with using bathroom or the kitchen and we felt very comfortable all the time.

We will definitely ask Aga for a room, while visiting Barcelona and will gladly meet her again :)
