Two colleagues and I stayed at Aga's apartment for a week to attend a conference. Aga was a gracious and generous host and the apartment was ideal for three people (there are even two washrooms). It was very comfortable and in a nice setting, easy access to the metro and the conference center (20-min walk), as well as cafes, tapas places, bars, etc. A good 'home base' for a trip to Barcelona. It was comfortable and private, making it ideal for our needs. I would heartily recommend Aga's apartment.
