Awesome friendly and helpful host. Accommodation and location excellent. Even after Finnair lost our suitcase for several days, Martin took phone calls and co-ordinated its return delivery for us. He offered tips on good cafes, restaurants and places to visit. Communication was always prompt and helpful and Martin even organised our taxi back to the airport. In all my travels, Martin has been by far the most helpful of hosts, even so far as providing tea, coffee and milk in the fridge. Thank you Martin for our great Berlin experience.
