The flat is perfectly located to visit Berlin, it's huge and bright. Perfect for 4 persons.
The little covered balcony is really a plus.
On the downside, the arrival is a bit disappointing: you need to get the key for a locker situated under a bridge where homeless people are sleeping and it seems that they are doing their business on the locker....
The flat would also need to be better cleaned: lot of dust on the bedside tables, shower curtain black with mold at the bottom.
Communication with the hosts was almost inexistant, Denis responded 2 days after each text...
Dishwasher was broken
