We had a great stay at the ben-simon apartment in Prenzlauer Berg. The neighborhood is fantastic and lively, and also exceptionally kid friendly. There's even a second hand toy store basically next door. One of the highlights of our trip was just exploring the area.
The only slight drawback was that we realized early on that the listing is from a company, so all messages sent by the host appear to be automated. It isn't a typical host interaction, in other words, but that was just fine with us. If you're looking for a more personalized touch, this isn't it.
Overall the apartment was tidy, instructions were extremely clear, and it's obvious that ben-simon apartments runs a really good and customer-oriented hospitality business. We had a great stay.
