The apartment is really nice and you will enjoy the view. What I really like is that Henry and Lisa response to my questions pretty fast so that I was able to schedule my plans.
A few points I want to highlight:
Nice view
Nice and clean bathroom
Two big mirrors to check out your outfits for clubbing (you gonna miss those stuff if you was in an apartment before with no mirror at all, trust me ;) )
Nice soundbox so you can listen to your favorite music
Nice couch, it was very comfortable while I enjoy my tee at the morning
One recommendation for my side, if you take the tram to the apartment from Berlin Main-station, look for the station Treptower Park, you gonna be faster than jump out by the station Ostkreuz or Warschauerstraße.
Thank you,
Felix
