Host was unprofessional, unwelcoming and rude. After a tiring day of touring Porto, we just wanted to rest. When we got to his place, the door to the apartment cannot be opened with the keys provided. Luckily he was inside, and tried to open the door but he too cannot open it from the inside and outside (used the window to get out). He then yelled at me and accused me for not using the correct key when in fact the other key provided (key to our room) would not fit in the keyhole so how can i use it? He then started trying to break the doorkey lock. Even the customers at a nearby resto helped opening the door but to no avail. He then sent a message that a guest broke the doorkey lock which I didnt. I merely tried to open the door using the key provided to us. He didnt even help us get inside the apartment (so we could eat and rest, we were very tired) and let us wait outside. He just told us that if we want to get inside we just have to climb through the window so we had to do our own initiative of borrowing chair from nearby resto so we (and otherguests) can get inside. He could have just said that the doorlock broke down and not blame us for the incident.
