The studio is indeed cozy and very clean. Chris was very helpful, specially since this listing was our first home in Berlin, so we had to deal with some bureaucracy. My husband, I and our cat stayed there for one month and were happy and satisfied overall.
The only problem we had was with the internet connection, which would be very slow and some times non-existent. Chris opened a protocol with the provider a few times, but unfortunately we just didn't get a stable reliable connection overall.
There are two supermarkets nearby and the polish restaurant under the apartments is quite good with a friendly staff, which was a plus :)
