If you're reading this comment, make yourself a favor and don't stay here. As you'll be able to see in many other comments, the recepcionist here is incredibly rude and unpleasant.
The information on the website is wrong, they say they speak English, French and Portuguese, and they only speak Portuguese.
Right off the bat, he charged me 60 EUR more than he was supposed to, even though I was showing him the booking on my phone, calmly. He started speaking very loudly and showing right in my face a piece of paper with the amount that he wanted me to pay, saying some things about taxes and more. I kept trying to explain that I had already paid for all additional taxes. He said started saying things about Spain and Spanish people that sounded a little racist, in Portuguese, and I couldn't understand most of it. Since I was tired and it looked like the situation was escalating, I decided to pay and go to the room and rest, and then later call Hotels.com to ask about information on what happened.
Then, the next day, when I arrived, he started SHOUTING at me and demanding why I had called Hotels.com! He threatened me and was incredibly aggressive and disrespectful. I tried to defuse the situation the best way I could, basically telling him that he was right in everything he was saying (which seemed to be the most important thing for him, being right).
I sincerely hope this comment will prevent someone in the future from having to go through the same thing.
