I'm giving 5 stars to raise the average (which I think is too low) but I would probably put a 4 or 4 and a half. The apartment is basement style, really cosy and "berlin style". Me and my friends really enjoyed the stay. + the location is nice, a friendly neighbourhood close to the metro and others transportation. The shower has definitely a problem. Has warm water, which is great but it always overflows, which can be kind of annoying, leaving the toilet floor always wet and inaccessible with socks. We weren't really bothered at all, but I guess it might be an issue for others people (especially for longer stays). Overall the experience was super great, we had fun in Berlin and the host was reachable for questions during the stay (it might seem that there are a lot of strict instructions compared to other Airbnb, but in the end is just small stuffs)
