Great communication with Host
The apartment is great at first sight, clean, functional and as described.
The apartment and host would be 5 stars all the way if it wouldn’t be for the exhaust/Airconditioning unit noise from the roof (belonging to the restaurant downstairs) penetrating the apartment especially at night to a level that sleeping becomes almost impossible. If you are young and go to bed late the noise eventually stops when the restaurant closes for the night (after midnight).
I hope that the host can solve this problem with the restaurant as this apartment and location is otherwise great!
