My mother and I spent 5 days at Javiers place, and it was perfect. He was very helpfull, told us about places to eat, what to see, how to get there and so on. The room was nice and clean just like the bathroom, and the apartement was situated on a cosy street with good restaurants and big trees on each side.
All in all I have nothing but good things to say about this trip to Barcelona - beautifull city, perfect host.
