The apartment was fine. Location was good and it was clean.
We had an issue with the TVthat was solved in less than 24hs.
You can only contact the host during working hours. In this time they answer either mail or WA.
We had a situation with the keys which turned out ok because we were lucky. We recommend always taking the keys when leaving the apartment, do not leave them in the safe because there might be some trouble coming in if someone locked the door to the building.
