Stephanie´s apartment is one of the best place you can book in Berlin to have a good experience there. The pictures shows everything as you can see, one REAL double bed in the main bedroom, one single bed in the living room, a complet kitchen and a bathroom with a very comfortable shower, even a little terrace outdoor.
The host was very comprehensible with us because we arrive late by a plane delay. We had a perfect wifi connexion, and information about visiting Berlín.
If everything was ok, the location was even better, it has M12 line Tram to 50m to the house, 200 m to the Underground, and many local to have dinner, have a drink and shopping (Lidl, Rewe,...).
I recomend the apartment without doubt.
