Martin was a top-notch host! Communication was swift and thorough from our first inquiry, to arrival and throughout our stay. Martin was extremely flexible and arranged early check-in after our long-haul flight. He was always quickly on-hand when we needed him (such as when we accidentally locked ourselves out!). He was very friendly and welcoming - everything we could have wanted! The apartment itself was ideal - superb central location, spacious and well laid out for a family. Martin left milk and bottled water in the fridge for us, tea, coffee and sugar in the cupboard as well as a bowl of fruit in the living room. When we return to Berlin we won't need to think twice about where we stay - thanks Martin!
