We were a group of 8 using Lanas apartment. Lana was easygoing and let us drop off our luggage before check-in time. No problems about the check-in/check-out. The apartment has a great location, 3 minutes walk to an U-bahn station and only two stops to Alexanderplatz. Lots of restaurants close by. The apartment was great, however if you are 8 people you must work a schedule for the bathroom as there is only one, but we managed it nicely. All in all a great stay, recommended!
