Thanks to Helen's tips, information and very lovely room, we loved Porto.
The location of the place (literally in front of the metro stop or 10/15min by walking to the city centre) was very helpful to discover the city. You have everything in the nearby and the room as well is provided with plenty of useful things: hairdryer, plates, cups, soap, coffee and tea, emergency kit and whatsoever. Bathroom is beautiful and so the room (nicer than in the pictures!).
+++ She was so kind that she waited for us up to almost midnight, welcoming us with typical drinks and snacks.
