Beautiful apartment. The 4pm check-in needs revising. Most flights from nearby Europe arrive midday. It's too long to be waiting. Upon arrival at 4pm, we found the apartment had not been cleaned by the management agency. This was not resolved until 6pm. We were in Porto for my birthday. This impacted dinner reservations as we had a long day travelling and needed to get ready. We made reservations at a restaurant hard to book at in city (Muu) which we had to cancel due to our awful welcoming and disruption. I asked for 1-2 hours late check out to compensate for this ruined birthday dinner and was instead refunded a derisory amount of €15 for the cleaning fee, which seems ironic as it wasn't cleaned. We only stayed for 3 nights anyway and to have our first and most important night ruined by a company who then provided an unsatisfactory compensation was highly disappointing. I loved the apartment but would probably go for a hotel next time rather than experience "LovelyStay" again.
