We loved this apartment - it was bright and airy with a lovely balcony and an amazing shared garden which would be wonderful if you have young children.
We have teenagers, but it was lovely for them too.
Unlike many airbnbs we have stayed in this is very much a family home and was very comfortable and great to relax in. The only thing I would say is there was nowhere to hang clothes as the wardrobes are used by Lothar and his family - this was not a problem for us but worth a mention...
The location is great - less than 10 minutes walk to two metro stations on different lines and easy to get everywhere we wanted to go. It is about a five minute walk to a street with all the shops you could need, a great indoor market and lots of bars and restaurants. It's also close to the old Templhof airport, the runway of which is now a huge park.
Lothar gave us lots of information about the area, and as he was away arranged for a neighbour to let us in which was very straightforward. Everyone in the apartment block was very friendly.
We didn't want to come home!
