Robert was amazing host, very friendly and warm. He will make sure we stay comfortably. He shared some good places to go and check.
His place is just 1 station away from Berlin central station, and in a quite residential neighbourhood which is a good point after your busy day outside.
Something to note though, his place is in the 5th floor without an elevator otherwise everything is perfect. I would definitely come back staying at his place again and would recommend to anyone visiting Berlin for a short/ long stays. Cheers!
