The apartment is sweet, comfortable, quiet and very clean. It's also in perfect location
There are no shades on the windows, so quite a lot of light comes in, in the morning.
Also, there is no Wifi in the apartment, which surprised me, but only because I took it for granted (it's mentioned on the listing page).
There was also an issue with the key, which required efforts from my brother, who was visiting Berlin in parallel, to go and get it.
