Lino's place is absolutely fantastic for a stay in Berlin. It is extremely well located, close to the beautiful neighbourhoods ("Kieze") of Kollwitzplatz and Mitte. Most tourist sites are reachable within a nice stroll along the canal or through the governmental center of the city. The apartment is located on the top floors of an old house located in the large backyard which is very typical for Berlin. This means it is extremely quiet and has a nice view into lots of greenery (in the warmer months) with a view of the iconic TV tower above the next row of houses. It has a large south-facing balcony which is great for breakfast, lunch and dinners or just hanging out. The apartment is distributed over two levels, with a large living room, well-fitted modern open kitchen and a small guest toilet on the lower floor, while the huge bedroom and master bathroom are on the upper floor. Everything is clean and well-stocked, and on top the apartment boasts a number of nice artworks on the walls from local artists.
Communication and check-in / out were fast, clear and without a hitch thanks to the amazing flat manager living in the same house on the ground floor - so any question or issues she will be able to resolve immediately. Only slight downside may be that it is 9 flights of stairs without elevator - so if you have bad knees or are really out of shape, this may be annoying. For us it just meant we got fitter while we were here :-)
We can highly recommend Lino's place for any sort or length of stay in Berlin.
