Great location and a very nice clean room (the "Cathedral Room"). And the manager handling the space was right on time to let me in for an early check-in, and super-nice. (In the end I was also given a late check-out -as no guest was booked the day I left- which was very helpful.) I would say that the Cathedral Room looks right out on to the street where kids gather to hang out on the lawn... so with the windows open you won't have total privacy. And there was construction during the day which was noisy and meant I couldn't really take advantage of the building's very nice outdoor area (although that's apparently a problem all over the city right now). And there was a circuit breaker issue that meant no hot water for a day or so. But I'll assume those were one-off issues... and again it's a very well-located nice place to hang your hat while in Porto.
