The appartment was clean and well-equiped. There were plenty of comfortable beds, I think I counted 7 or 8. The place was well-heated, spacious and comfortable. It looks like the pictures.
Plenty of nice restaurants, shops and supermarkets in the neighbourhood. It is easy to get around by tram or other public transport.
Flo responded quickly and friendly to all our questions and provided help fast when the wifi didn't work on the first day. Online check-in worked well.
Only remark would be that although the kitchen is well-equiped (fancy coffee machine with coffee beans, microwave, watercooker, plenty of plates and glasses etc) it is not really suited for cooking a whole dinner meal. There is only one spot on the stove and no oil, salt, pepper or spices. A dishtowel and some extra toilet paper would also have come in handy.
Overall, we are very happy with our stay.
Tip: parking in the schönhauser allee arcade mall is around the corner and costs only €5 per day!
