Had a lovely time in this unique and wonderful apartment. The location was perfect with lots of cook shops, cafes and restaurants nearby, and it was also really easy to get to other places in Berlin with public transport! The only "negative" thing we could point out is that the bathroom is very tiny. Also there is a kindergarten right next to the apartment which made quite a lot of noise in the mornings, but we knew of that beforehand and brought noise cancelling headphones so it wasn't really an issue.
Overall we would definitely recommend booking this apartment for your stay in Berlin! 😍
