Expensive shack.
Secondary bedroom was the size of a matchbox, they even had to trim a pillar in order to place the bed, which took more than half of the space of the room. In that very bed slept an 1'60 tall adult that could barely fit inside. Mattress was very bad, made of 5cm foam.
Worst thing was security: there was a numeric keypad on the street to access the building (the door was open almost every time), and another keypad to access the flat. They never gave us a key, and the access door only had the small latch that even a half-brained thief could easily open with a card.
Kitchen was a sink and two electric hobs that we never used. The fridge, one meter tall, was hidden inside a wardrobe in the lounge (never mind, you'll locate it by the noise it makes).
Another thing to bring into attention was the noise of pipelines, no matter if it was you using the water, or any of your neighbours. You could hear that loud noise anywhere inside the flat. They gave us only one soap bottle, that you could use for hands, body and hair (as mentioned in the label).
They made us fill a lot of personal information prior to the access date, including the data of the flights, but then they never gave any help or information when requested.
WiFi is included in the price. The one star we give is for the location at Oporto, really really good.
Summing up, it is terrible overpriced.
