Danilo is a really friendly and helpful person! I really enjoyed my stay in his flat. It has everything one needs.
The only things I want to mention is that there's a bid of mould on the ceiling in the bathroom and the wall to the next room (also a bedroom which is for rent/airbnb) is really thin, so you literally hear everything the person(s) in the other room are doing. So better bring earplugs.
Thanks again for making my stay in Porto so convenient :)
