The biggest plus of this apartment is Alina, who was super communicative and helpful with our challenging check-in and check-out schedule, including offering a place to keep our luggage after check-out if needed.
The apartment is nice and spacious, though the neighborhood isn't the prettiest you can find in Berlin.
It is also a bit far from the U bahn stations (10-15 min walk to the closest ones), but there are a few bus stops close by.
The mattress is on the softer side for those who these things matter to.
A minor problem we had was that the towels were brand new and weren't pre-washed, so everything (including our respiratory systems) was full of micro towel fibers (this should only concern the next few visitors, as there seemed to be quite some spare towels and it might take a while before they all see use, but eventually it should pass).
The bigger (not to say BIG) problem was that there was no way to balance the water temperature in the shower, which meant you could either have a cold shower or a boiling hot one.
We asked Alina to take care of this, but unfortunately, after sending a handiman to check it out, the answer was that there was nothing that could be done while we were still there as it had to do with the piping system of the entire building.
We would highly recommend verifying this problem has been taken care of before booking this property, as this issue dampened our experience.
Considering those two issues are taken care of - it's a place worth booking if you're on a tight budget and a bit of walking distance doesn't bother you.
