It was our first time in Berlin with my friend, we spent 4 days at Gustavo's place. We did not get the chance to meet him personnally, one of his friend was there to meet us. Gustavo was always available, very communicative and gave us all the informations we needed about the apartment. As mentionned by the other travellers the place is indeed clean, cute and well located. I highly recommend this place! Again thanks a lot Gustavo! :)
