Olexandras flat is even bigger and more beautifull than in the photos. Its located in the coolest, most fun place in berlin, espacially for young travelers. We felt so good coming back to the appartment every night. There are tons of bars, clubs and restaurants at walking distance, and many people in the streets until late at night so as two girls we felt very safe. Theres a great organic coffe shop right across from the flat and its great for breakfest.
Olexandra was very nice and kind, and very available. Everything was just as we agreed with no surprises at all. The flat was clean and neat and it feels very homie with a lot of light.
Even with all thats going on outside it was very quiet in the flat and we had a great night sleep. The bed was also clean and comfortable.
The bathroom was comfortable to use even though its small as can be seen in the photo, and there were allways warm water, plus its also beautifull! You can feel its the home of a designer:)
One thing i think you you should know considers the door. Its an old wooden door (all the flats in the building has this same kind of doors) with an old lock that didnt seem very strong. Yet, there is a heavy lock on the door downstairs (the intercom) and there were no intruders at any time anyway. So we actually felt very safe, i just think its something you should know.
In general it was the best we could have asked for, and we had the best berlin expirience much thanks to this appartment, so i extremely recommend it!
