Well appointed apartment in NW Kreuzburg, less than 10 minutes walk to Checkpoint Charlie.
We stayed during July, which had some very hot days (90 degrees F). We were a little concerned about the lack of air conditioning, but the apartment has great windows for airflow and we were always able to keep the temperature reasonably cool during the day.
Pros
* Location is very central. Can get anywhere in Berlin within 30 minutes on public transport - north, south, east, west.
* Decent grocery stores within walking distance.
* Laundry in the building (4 euros to wash, drying clothes is free)
* Kitchen is well appointed with the basics
* There’s a rooftop deck, with great views of the city.
* Lots of natural light during the day. Blinds and curtains help block out the light when sleeping. Still, eye mask is recommended if you are a light-sensitive sleeper.
Cons
* Being close to the touristy area of Checkpoint Charlie was a little annoying. Lots of tourist trap junk. We spent most of our time and meals elsewhere. Exceptions: the vegan cafe on the ground floor is amazing (my gf and I are meat eaters and we loved it anyway) and Delhi 6, an Indian restaurant around the corner.
* Jewish museum is behind the apartment. Visiting children Tuesday through Friday can be quite noisy if the windows are open. We used a “white noise” maker app to cover the sound.
* Concrete floors can be rather cold, even in summer. Bring slippers. There are floor heaters, which help make this more manageable.
Other items of note
* Bed is medium firm. Pillows are extremely soft and squishy. These did not match my personal preferences, but yours might be different.
