John's flat is really gorgeous. The photos do it proper justice now (I think they we're updated during our stay). The flat itself is very new and very clean. It is very spacious and leaves a lot of room for all guests to hang out or have their own space. The bathroom was really nice, and the shower had great pressure. The balcony and the backyard were both lovely additions to the home and were well kept.
The flat is in a very residential area - I usually stay in Neukolln/Kreuzberg area and this was much much quieter which was very positive. There are a ton of restaurants walking distance but the transit link is also walking distance if you wanted to go further.
Key pickup was very easy & organized by airgreets who are very professional and communicative.
I have stayed in Berlin several times and Johns airbnb was very comfortable and really wonderful. I would recommend this airbnb to anyone, and I also think its important to note that this would be a good family Airbnb.
