This apartment was amazing! It was VERY clean and quiet, and just as it pictured. It was the perfect place for us to get a good night's rest after long days of sightseeing. The neighborhood is safe and quiet, and is perfect for getting a feel for life in Berlin. Thanks to the link provided by the hosts, we were able to research public transportation in Berlin (BVG) and used it almost exclusively during our stay. We purchased a 4-day Berlin Welcome Card at TXL, and it was well worth it. The M4 and M10 tram stops are very short distance from the apartment. Alexanderplatz, a central point for U-bahn, is just 8 min away by M4 tram. We did a lot of walking as well, especially in the Kollwitzplatz area. With several options for grocery shopping nearby, it was easy to buy things to make breakfast every morning, and buy fresh fruits for snacking during our sightseeing. Despite the modernity of the apartment, it felt cozy and we immediately felt right at home. Our only regret is that, because of our short stay, we were not able to enjoy some of the amenities in the apartment (like the amazing rooftop view). The hosts are very quick to reply, and are extremely detail-oriented (especially with check-in instructions)... which was very much to our liking. In that respect, I wish I could give them 6 stars. We would not hesitate to book this place again for our next visit to Berlin!
