Sorry for the late feedback. Federico was away when we were in Barcelona, but Louise was there waiting for us and gave us the keys. Though she can not speak English, but we still figured everything out and she was very nice and helped us with luggage the last day after checking out. The apartment was quite near L3 and is quite convenient for going everywhere. But there exists two problems, one was that the apartment was located just by the road and the sound insulation of it was far from good, we can clearly hear cars passing by in the late night, so, for people have high demand for good sleeping quality, you might need think it carefully....the other thing is the poor wifi....we could not even find the signal...so....that made our journey quite inconvenient....
