I felt very welcome and it was great that they managed to host me even with so short notice. They even managed to get me a table to work in the room
I didn't have a closet assigned but the room is big enough so I could have my luggage around.
Also, the location is better than it may look in maps. It is a 10 min walk from the night area, and there are several local restaurants for inexpensive and authentic Porto meals right at the door. Pedestrian area 5 mins with a couple of local brewed beer. 20 mins walk from Palacio Bolsa and direct train line to the airport. 3-6e Uber 10min.
