I went to stay at Charlotte's apartment with my boyfriend for 3 nights. The photos don't do the apartment justice. It is bright, airy. spacious and absolutely spotless! Charlotte was great at communicating with us and couldn't have been more helpful.
The flat is equipped with everything we needed, and it very close to the S-Bahn which meant it was a prime location for us to commute in an out of the city centre.
Definitely consider staying here!
