Unfortunately our stay at Vladimirs apartment was not as expected. He didn't reply to my messages regarding how we should proceed in order to hand over the keys. So when we arrived at 11pm in Berlin, as i told him several days before via Message, no one was around infront of the apartment and no additional information was giving to us. So we tried to call him 26 times. After that we tried to call the concierge (the number was on a sign infront of the door) two times. Nobody answered the phone and we waited infront of the apartment with our suitcases for over one hour in the cold with no place to sleep. So we booked a hotel near that area and the next morning Vladimir replied to our message. Saying that someone was waiting for us in the apartment and also went outside to check if we were there, which wasn't true since we were waiting outside the door for over an hour and nobody came. he offered us 100€ as compensation, but we payed close to 200€ for that additonal hotel night and lost one night at his apartment. So we reached out to Air bnb directly, luckily their costumer support is amazing and a friendly women helped us out and handled everything regarding the extra costs, and we found a solution. However, when we arrived at the air bnb again (the next morning), Vladimir said that we can pick up the keys at the conceirge, who didn't had the keys! So we reached out to him again: He said that a lady called masha will bring us the keys now. So we had to wait for 45 minutes in the hallway for Masha to arrive. When we were finally able to get inside the apartment, everything went fine. The apartment is in a good condition, it was clean and very modern. Actually a nice apartment. But since the communication was super difficult and we lost a lot of time which we rather would have spent for exploring Berlin i cannot recommend to stay at Vladimirs apartment. It was really a frustrating experience and our Berlin trip started with such a negative experience. I hope Vladimir will take more care of the communication and especially the check in with his future guests so that this won't ever happen again.
