We stayed at hotel 103 for 1 night, greeted by a nice man on reception. Room was basic but clean and comfortable, good areas with pool table and Xbox downstairs to chill in plus bar, easy to get to from Schonefeld airport and easy to reach surrounding areas. There's plenty of bars/restaurants and shops literally on the doorstep. Helpful staff, another man on reception recommended we go to Aleksander Platz which was a great day out. My only criticism is that the door is difficult to open with your card. There is a technique to open it which the staff show you. Sometimes it doesn't work. Although the staff were very helpful to help if you got stuck with the door. Overall, very nice and the owner is a nice man. If your looking for somewhere clean and cheap as a base to explore Berlin I would recommend this hotel.
