Timo's appartment was perfect for our 4 days stay in Berlin. It is literally a few steps away from some of the most interesting places in the city, while still being located in a quiet street which is great to ensure a good rest at the end of the day.
You will find groceries, cafés and restaurants just a few blocks away, when not a few steps away.
The appartment's equipment had everyrhing we needed to make some cooking and have one or two meals a day "at home". Beds are comfortabe and accomodated perfectly to our family (couple + 2 kids).
Timo and his wife were very responsive to our extra needs.
I strongly recommend Timo's place if you are visiting Berlin with your family for a few day.
