We really liked the place. It is located very conviniently near U-bahn station and in 5 min walk from Tiergarten park. In close proximity to the building there is a small foodstore, supermarket REWE and cafes(near U-bahn).
We were met by Johannes and he was really kind and helpful.
The building itself is very clean and surrounded with green gardens and trees.
Flat is not too big, but was clean and overall good. There is a balcony with table and it's lovely for breakfasts with birds singing in the trees nearby. Flat has all the necessities like hairdryer, iron, microwave, washing machine (though located not very conviniently behind the wardrobe, big people might have problems using it), tv, teapot, everything. Bathroom was not the greatest but usable.
Overall it's a great place in the "green heart" of the city! Thank you, we had a great time!
