If you are expecting to be out and about exploring Berlin most of the day this is a perfect place to stay. Great value for money and close to shops and transport links into the city. The room is comfortable and has the basics you would expect but only a little hanging space for clothes.
The bathroom is great and the kitchen is good for making simple snacks or drinks. Everything is very clean but the kitchen is still a work in progress.
Dimitri is very friendly and helpful but wasn't around much as he works really hard and long hours. But he always responded to texts and messages really fast and I am sure would sort out any questions or problems you had very quickly.
Because I was visiting friends nearby it suited me really well just to be able to come and go and the bed was comfortable for a good nights sleep.
Being on a main road isn't a problem as the apartment is at the back and you aren't aware of any traffic noise until you leave the building.
