Even though the location was great, the service we got after reporting quite a lot of problems, wasn't sufficient. We travelled in a group of 7 btw. We had so many problems with this flat, we want to share the main ones with you: this flat in particular came with no working heating, in the Berlin winter this means you will freeze. If you have kids, are a bit older or pregnant you should consider a different accommodation - one of us returned with a cold and we consider ourselves young & fit. The only warm and cosy spot was the en-suite bathroom because it has underfloor heating. The host did send someone around to check, he said it was cold and we should drink more to keep warm while offering us prosecco on the house.
The wifi is shared with other flats in the building - we had to buy data so we can hotspot from our phones, at no time during the day was the internet was even good enough to send an email with no attachment.
The shower wasn't draining properly from the start, the technician checked and found broken glass in the shower.
Later when most of the problems we had were resolved except the heating problem, the host accused us of many things including wanting to get some money back because we contacted him so many times. We only contacted him because we were still freezing. He didn't believe it was too cold, said it's normal in Berlin although the en-suite was perfectly warm - we spent too much time in there. He continued to also accuse us for being responsible for the broken glass in the shower, too.
contacted Airbnb after we left the flat to share our poor experience in the flat and with the host. Tip to those that have bad experiences: don't stay until the end of your stay. Contact them while you experience those issues. It will help to come to a better resolution.
We don't recommend this place/host.
