Everything was fine. Michael is a very good host, we communicated well and also shared a good chat.
The apartment is very close to the S-Bahn, and from there circa 30 min to almost everywhere. There is also a LIDLE by 500m.
The room is as you see in the pictures. Small, but cozy. A little hot, but ok. There is a tiny ventilator that suits fine.
I would recommend this room for short stays, maybe 5-7 days, then you start missing regular rooms.
I recommend Michael's house and would totally be back again!
