This place is amazing!! Great location in Berlin, 2 minutes from the u station and 5 quick stops from alexanderplaze. Andreas gave us great tips which proved to be amazing. The apartment is clean, cool, full of maps and books about Berlin. The water is hot, the bed is comfortable and it's quite at all times.
If you have mobility problems or very heavy baggage, take into account that this is without an elevator. Andreas helped us with the luggage so no problem there either for us.
Can't wait to come back again.
