Great value apartment in a fab location - it's a lovely quiet residential street but within a couple of minutes walk you are at all the bars/restaurants/sights of Kreuzberg. Check-in was super easy and Constantin was very helpful. The whole flat was spotless; also really appreciated that shower gel/shampoo/tea/coffee were all provided. I saw in previous reviews that people had mentioned the small bathroom; it IS small but this didn't bother us at all (even as a group of five). The shower was always hot. Definitely a good spot for a group visit to Berlin!
