I highly recommend staying at Maria's apartment when in Copenhagen: it is exactly as described, spacious and cosy, very central, and communication with Maria is very easy.
We even met Maria upon our arrival, she was very lovely and welcoming!
The bathroom is indeed very small, but functional, so it is not a problem.
Overall, the apartment was very comfortable and clean, it was nice to come home to it after a long day of sightseeing.
Thank you Maria!
