My stay with Anderson and Guido could not have been better! They are such warm, welcoming and fun people who made my visit extra special. They have a lovely home, great personal balcony for guests and many useful tips! The U station is just a block away for easy access to the city sites. I highly recommend you have international cellphone service or use a Sim card (wait for help from Anderson) and download the Berlin Subway app. Take their advice to start with a trip on the #100 bus line to get acclimated...and don't miss the German Historic Museum (one of the best I've ever been to) as well as the 3-hour boat ride that departs just blocks from their home. As a frequent Airbnb user, I have to put Anderson and Guido's place at the top of my list of favorites...very special hosts!
