Maria is a very friendly host, always happy ho help with advice on what to see in Porto. The apartment is very conveniently situated in the new centre, it is very quiet and you can easily walk to the old town. There are a lot of public transportation means at max 5 minutes walk. Her cats are super sweet and very well educated :-)
However, the room is very dark and very humid, and there is a lingering smell of damp which makes it very unconfortable, and which goes deep in the clothes. It is also a very cold room, even when outside the temperature is 25. Overall, eve if Maria was super nice and communicative, and the apartment is central, i would not recommend it for a holiday in Porto.
