Marios Apartment looks exactly like the photos. I had a nice time in the apartment. It was mostly clean besides some hairs in the bathroom and some crumbles under the table. The kitchen is well equipped but I ate almost every day outside in the city so I didn‘t use the most of the equipment.
The location of the apartment is the best to start the sightseeing in Porto. Also you can easily go to the train station São Bento to take a train to Aveiro, Braga or Guimaraes.
When you don’t have a deep sleep you should take some ear plugs with you because the windows are not that much isolate.
The communication with Mario and Raphael were very fast and good. Also I got the chance to bring my suitcase to the apartment before the check in time.
