Andreas is a great host. He took proactively care that everything is clear and well organized, i.e. gave me calls prior to our stay, made sure that he can be reached via the phone of a friend too just in case etc. Moreover he surprised us with delicious welcome appetizers.
The flat is brilliant, quiet and exactly as described. There is a lot to discover, if you take the time to look at all the fancyful installations. Berlin style at its best. The location in the city is ideal. Public Transport and all the shops you need are nearby. I highly recommend Andreas and his flat.
