We stayed here for a few days while in Berlin. This apartment was perfect for what we needed: quiet space central to/close to Shoneberg, Kreuzberg, Tiergarten. For those of you who are LGBTQIA+ like myself, this is a perfect place to stay as it's right in the center of the most historically gay neighborhood in Berlin and on the same street as some of the most popular bars, bookstores, and spaces.
We chose the apartment because we needed two separate rooms. Both the living room and the bedroom proper had comfortable beds and private closing doors. We were amazed at how quiet the whole place was--we could hear the birds chirping every morning. The kitchen was furnished with the basic essentials--seasonings, electric stove, coffee machine, toaster, microwave, fridge. There's a supermarket right across the street and several others close by.
One note for accessibility: the apartment is on the top (5th) floor of the building. There are stairs and an elevator, but even with the elevator, there is a half flight of stairs to get to the door of the apartment. This was no problem for us, but worth noting for people with accessibility concerns/needs.
The host Laurentiu was very communicative and flexible on check in and check out times. Their friend, Rainer, met us at the apartment for check-in and not only walked us through all the basics, but also sat down with us and marked up a map with places to eat, drink, and visit. He was super helpful and made us feel very welcome. He even helped call a taxi company to schedule pickup for the day of check-out to go to the airport.
Overall, a lovely stay, albeit short. If I am in Berlin again, I would happily rebook.
