The mattresses are firm and comfortable
The flat was clean, nicely decorated and had high quality finishings.
The biggest problem is that when filtering for 1-bedroom accommodation, this flat appears on the list, being actually a studio. In the description or title, the word studio is not mentioned either. The size is advertised as 45m2 but it's really 30m2.
It's not worth €110 a night. Possibly €80 but not more.
The bathroom has a damp smell (pipes, sewer).
