My family and I stayed at Gabriels place in Berlin for 3 days. It was a great place! Very spacious, bright and clean. The apartment is located in a quiet backyard by a very charming street with small shops and cafés. It was easy to get around Berlin from there. Grabriel has been very helpfull, answering my pre-traveling-questions very quickly. We never met him in person but we easily got the keys from his sweet stand in, Katja. I can highly recomment this place :)
