Denis did not manage to let us into the house. He forgot to send us the code to enter and did not reply to my messages and the phone number was a wrong one. We ended up cancelling (!) the trip and went back to Lisbon after waiting in front of the house for 2 hours in contact with Airbnb. No answers.
Maybe he just forgot on this special occasion but it is totally unacceptable as a host.
The next morning I woke up i got a text by Denis with the code. He apologised and offered us to stay anyways but of course we did not want to stay at his place after that.
Being a host is not easy - good luck for the future Denis.
