DO NOT STAY WITH THE PORTO CONCIERGE! Not at this flat or any other. This place was extremely filthy with hair, dust and crumbles from food. More so, I found multiple pests (most likely kitchen pests) inside the apartment. Told them immediately that I wouldn't stay and after telling them, they stopped answering my calls and slowly answered my messages. Airbnb was luckily able to confirm the cancellation after half of the day had passed and they were able to make the host cooperate. In total, I lost a days worth of work dealing with this issue. As they were refusing to change my stay to another of their flats since there was a price difference (on +8 euros a night) I once more booked through the hosts as there was limited options for the short notice. This time the apartment had a broken frontdoor lock, making it impossible for tenants to enter / leave the building at all times. We ended up keeping it open as we were concerned of our safety. The Porto Concierge is putting their tenants safety in jeopardy and will not cooperate if shit hits the fan. Save your time & money by booking something else!
