It was not the best operation in terms of the check-in/booking experience. When I booked I had requested an early check-in and the booking was accepted so I thought it had been arranged, only to be told a day before my arrival the earliest check-in would be 14:00. This was obviously too late to cancel the booking penalty-free.
After dropping off luggage I was told the again the apartment would not be ready until 14:00 and so went out and about to kill time. I returned to the office slightly early around 13:40 to be told it still wasn’t ready, the person didn’t even check, this just seemed a far cry from the “flexible check-in” which they advertised on here.
The studio apartment was okay, good location (close to metro) supermarket nearby. Snags... some kitchen doors were loose. No wine glasses for the thoughtful complimentary wine. Bed was comfy, linen was spotless, towels were provided but lacked a good sized bath sheet towel.
Would I stay again, in Porto definitely but possibly not with The Porto Concierge (they have over 700 apartments in Porto on airbnb).
