I want to thank wilma for helping us with 2 separate keys, which made it easier for us to navigate the city separately as we liked.
The room was a bit surprising in comparison to the pictures, it had been rearranged with a much smaller table, and there were some interesting decor choices not in the pictures. As the table was an important aspect for us, Wilma refunded part of the payment, which I appreciate!
Also the space is primarily 1 room (sleeping room) that you walk straight into, with a small kitchen & bathroom built into 1 corner as a room in the room. It is listed as a loft (usually an upper floor) but it's actually a ground floor which I didn't expect.
A small issue because of this was that every morning a truck came at 6-7am to drop off food or pick up trash at the neighboring grocery store, and made a very loud continuous peeping sound for about 10 minutes directly outside our entrance. Not something Wilma can solve, but it was quite frustrating for us.
If you're planning on visiting east berlin or doing lots of touristy things, it is quite far west (watch out coming back late at night, sometimes connections on public transit were difficult), but it was very nice on the hot days when we were close to lakes and forests!
Hope this helps others make an informed choice!
