Anca's place is in an amazing pocket of Berlin, with direct transport links to Neukölln and free on-street parking within the immediate area. With Bergmannkiez located nearby, and easy transport links to the city centre, it allows you to take advantage of local and city-wide options.
The space was a lovely upper floor conversion of a cottage, located within the inner courtyard of residential apartments. This meant it was extremely well sheltered from street noise, and offered a big open space which was very comfortable for us (a couple) plus lots of lots of additional space for storing bags/ coats etc so they weren't in the way. Our stay was at the beginning of the infamous Berlin winter, and while Anca's place was an old cottage which naturally had some draftiness, the heating nontheless worked quickly and efficiently and created a cosy, dry and warm environment for our evenings in.
Highly recommended for a unique place you can call your own when visiting Berlin, and please treat the space respectfully as it's clear how much work the family have put in to making it a beautiful place to stay.
