I would love to give this lovely apartment a good review - location is perfect, the host is great and the apartment is presented really well. The master bedroom was good sound wise and if that's the only room you need then this place could be perfect for you.
However, the ventilation system / air conditioning is a loud constant in the living room with no visible means to turn it off or down. A constant drone can be anxiety inducing for some folk, myself included, so it's really important to know about before you book.
But the part that dropped the score to a 2 is the lack of sleep available if using the bedroom with single beds. In the evening the interior wall of this room literally vibrates all night from whatever system runs so loudly all night long (like a bathroom extractor fan but there was no such fan). Even earplugs were not enough to cover this sound sadly.
Again everything else is lovely and the master bedroom is fine!
