I would have to say my stay at this apartment was really good because :-
1) Hosts were very responsive. They cleared my doubts before booking. And very responsive even after booking. They kept checking if Iam having a good stay or not , or I need anything else. 5 stars for it
2) Very clean apartment with all the facilities you can ask for and very spacious room too.
3) Location was very near to Ubahn red line (U1) only 4 mins walking and it can take you to all major attractions in few mins and it had a supermarket too just outside the aptment
Worth every penny. Thanks guys
