Wrote a private message to the host but never got an answer so here it is:
Hello, Just wanted to give some feedback.
We loved the architecture of the house, however the place did not meet basic hygienic criteria. There was an old blood stain on the sheets as well as other stains on the sheets and the were also small insects, both dead and alive, crawling around in the bed. Not knowing whether or not the insects were bedbugs (as a doctor I see the bedbugs quite often with patients) we decided to not sleep in the bed and left abruptly at 11.30 pm to check in to a hotel close by.
Must say that I am bit disappointed by that and cannot say that I am pleased with the booking
Apart from the bedroom (had an AC) the house had a moldy smell..
As hotels/airbnb are quite cheap in Granada, I would recommend to look elsewhere for accommodation
