Great location and clean, but noisy at night and poor check-in communication.Pros:The apartment is spotless and genuinely in the heart of Porto, with everything you need within walking distance.Cons:The windows aren't well soundproofed, so on weekend nights we could hear people shouting in the street until about 3 AM. The main bathroom also has no exhaust fan, so steam and humidity linger after showers.Check-in communication was the biggest problem. The listing and Vrbo say instructions are sent a few days before arrival. We never received them. I messaged the host the day I booked (16 days before check-in) and again two days later with questions about the unit, then once more two days before arrival asking about check-in, and got no reply in the thread. I had to contact Vrbo customer service, then message and call the host on WhatsApp to get the details. Once reached, João was pleasant and helpful, but this was avoidable stress when traveling abroad.If you're booking here, bring earplugs for weekend nights and expect to chase the host for check-in details.
