Thanks to Alessandro for providing swift responses. Also, arriving at the apartment was as easy as it gets - we simply arrived and was received without even have to call in advance, as he had been checking out our flight arrival. The apartment was very nice. One of the beds is in a room adjacent to the living room without a separate door, which I had noticed in the reviews and which was no problem at all for us. The AC worked well and silent.
Would be happy to go back and can fully recommend!
