Robert is a veteran host, and you can feel it. Communication was flawless and near instant, there was a bottle of wine on the table and there where clear written instructions for the main things like the dishwasher and the TV.
The souterrain flat has everything you might need for a couple of days.
Especially the kitchen is well equipped with pots and stuff to a degree that I felt supercedes what I have come to expect from AirBnB places. There is even a hand blender and a mortar and pestel!
We all felt the spacious shower was the best thing about Robert's flat.
The location is reasonable for a giant city like Berlin, S and U Bahn stations are nearby. If you have something going on at or near the Olympa stadion, this is the perfect spot for you.
Check in and check out were hassle free. We were lucky enough that our stay wasn't sandwiched by other guests, so Robert was quite accomodating in that regard.
So, great host, great place!
