We stayed with Nico and Anne during a short trip to Berlin and had a wonderful time. Both were very sweet - also to our dog Alba (even after she snatched their smoked salmon on the first day!). Nico had some great tips on how to enjoy the city. We liked the area a lot and were able to walk to all the big sights. Super convenient location and much more affordable (especially if you get paid in pesos!) than many other options. We highly recommend staying with Nico and Anne and would return any time!
