Was welcomed by Alberto's friend, who was incredibly gracious and friendly. We never met Alberto, but he was easily reached via text or messaging on the Airbnb app. The space is beautiful-high ceilings and hard wood floors. It's right in front of an old airport that's now in use as a park. Great area to go for a run. The station is a five minute walk away and takes you anywhere you would want to explore in Berlin within 30 minutes. Great place!
