I got so angry with The Porto Concierge because they didn't answer my messages. Once I arrived to apartment no one was there and no one answered. I had to find the contact through Google. Again they didn't answer the phone and I finally contacted them through a chat on their website. They informed me that I had to pay a taxi to go their office to pick up the apartment keys. If I knew that before I wouldn't booked with them. Of course I was very pissed and the experience was very frustrating. By the other hand the was clean and comfortable.
