I highly recommend staying at Maria's place. The apartment is beautiful with great amenities and comfortable beds. We were able to walk to gothic quarter and other major parts of the city. Its easy to grab a taxi right outside the apartment.
Maria was responsive and greeted us at the apartment to give us a tour so check-in was super easy. She may ask you for all guests emails but its just to ensure that everyone gets her instructions and recommendations which was helpful for our group.
