About the room: It is very well prepared, you can easily come here from the airport by bus 602 or by the subway. Also it is easy to catch a bus to the centre, if you want to. I did not because I prefer to walk on foot and the place is not too far from Almada. Also, the neighborhood is really safe!
Luisa greeted me for the check in and she is really amicable! My Portuguese is not so good, but she tried her best using simple vocab to explain things for me, and it worked, since I understood almost everything she said.
Cesar is one of the most genial and reliable Airbnb hosts I've ever met. He assisted me in learning not only the Portuguese language but also the culture, the working and start-hub scene in Porto. He will come in the evening to do the check in or to ask whether everything is fine. It is also easy to communicate with Cesar.
If you need something, Luisa and Cesar will be there to provide support.
