I was in Pilar's house for one day in the single room. Everything went smooth, Pilar speaks a little English so we could communicate fairly well. Both Pilar and her son Arnau were very nice and helpful in giving me some touristic suggestions about what to see and do in Girona.
The room is exactly as in the photos that I had seen. A wifi connection was available as well as an air conditioner very close to the entrance of the room. If I ever happen to be in Girona again some day in the future, I will certainly try to check the availability of the accommodation at Pilar's house.
