It's been a fantastic stay at Songfrei's place. We deem ourselves really lucky to find such a place and hosts in Berlin.
Andrea, who's been handling all the correspondence, check-in and etc, from the get-go has been very accommodating, communicative and helpful with the whole process.
The location is exceptional. The unit is located in a compound that's renovated from an old hospital with outstanding taste and skill. The unit overlooks a fairy-tale park in the hearth of Kreuzberg. The neighborhood is as 'Berlin' as it gets with all it's charm. Only thing that needs to be noted about the location may be that the map on the AirBNB listing was showing the wrong area at the time we booked it (Mitte instead of Kreuzberg). This error was not a problem for us at all, since the actual location was much much better than the one on the listing suggested.
You can find anything you might need in the unit to enjoy your stay. Extremely accurate pictures on the listing. Anything that may come up and you need help with, Andrea is always there promptly with a convenient solution.
We would book this place on a heartbeat in the future and we sincerely hope to do so.
We strongly recommend this unit!
