Top clean, very flexible (Janet offered me a very early check in), Janet is very serious, nice and helpful (gave me a map and some tips, etc.). The appartment is very well located (2 min from the bus or train, 5-10 min walk from the Brandburger Tür and the Reichstag, even closer from the Tiergarten. Was excellent not only for work but also for tourism. Completely quiet at night, very good bed with great pillows. Bathroom new, design, big, and again perfectly clean. I will come again to this place if I come back to Berlin.
