I spent one month at Charlotte's place and had a great time. The location and access to public transportation was most important to me. The S-Bahn is a quick walk down the block. U-Bahn is also nearby and bus service from Innsbrucker Platz or Breslauer Platz is super convenient. The apartment is very clean and has everything needed for a short or long stay including a nicely equipped kitchen. There is a sunny balcony to enjoy morning coffee. I appreciated the cross ventilation that kept the rooms comfortable even on warm days. The apartment is as described in the listing and is suitable for 1 or 2 people. Check in was very easy. Charlotte is fluent in English and other languages. She provided maps and recommendations for the neighborhood and all of Berlin. The apartment is attached to Charlotte's place but it feels very private. Charlotte gives as much privacy as you want. She is a fun and interesting host. I would love to return to Charlotte's place. Highly recommended.
