Max's flat is stunning, incredibly spacious and spotlessly clean. Also cosy, well-located and incredibly quiet at night.
We came to visit the Christmas markets, and Max was such a friendly and approachable host - he gave us detailed instructions on how to pick up the keys, and offered great tips on where to eat and what to see. He was overseas while we were there, so we didn't get to meet him, but he responded pretty much instantly to queries.
Overall, I can't think of a single thing I'd change! When we visit Berlin again (which we will - it's a fabulous city), Max's flat would be my first choice to stay in. Thanks again, Max!
