I will try to answer as far as I understand, since I don't speak portuguese. Yes, I guess I was not very friendly because I was surprised to see 5 people and a young child. I had problem with my neigbourghs because of the noice of children. If I had known, I would have said no.
It already happened that I left the flat only at 6. pm and my hosts completly understood and were fine with that. The fact is, I leave and work in my flat, that's why I dont rent it at an expensive price whearas I'm in Paris.
I'm suprised the flat was not clean because I pay someone to do it. All the other hosts were happy with that. The person came before I left. I didn't check everything after but still. It was not very dirty anyway. May be it's because the bath is a bit old and there is marks that i cant clean.
Any way, this group harldy speaks english. I guess this is the main reason why there was a bad communication between us. Shame that they had a bad experience of my flat and of Airbnb.
