From the first email Andrea went out of his way to make us feel welcome. He responded to every message warmly and promptly and was available throughout our stay. The apartment is beautifully appointed, perfectly located, and full of welcoming touches: there was even a 'Welcome Home' sign on the fridge. He provided a local iPhone, and it was fully charged. He placed the laundry soap by the washer, so even if we didn't know what 'wachsmittel' is we could easily make the connection. There were bottles of chilled mineral water. There was housekeeping mid-way through our stay. No detail was overlooked-- he thoughtfully and carefully prepared for our visit, and it showed. We loved everything about this apartment and will happily stay there the next time are in Berlin. It is spacious, gracefully decorated, and had plenty of storage space for our things. It is located in a warm and friendly neighborhood with plenty of dining and shopping within walking distance, and is also close to all forms of public transportation. The apartment is in an elegant, beautifully maintained pre-war building. And it's reasonably priced. If you need a one-bedroom in Berlin, this is the place.
