João and his wife were exceptional hosts. We arrived later than the agreed upon time as our flight was delayed. Without the ability to notify João we were concerned he would be agitated, but such was not the case. He was very patient and polite, giving fabulous suggestions of what to do and see in Porto and offering sparkling wine as a welcome. The apartment itself is clean, lovely, and very tastefully arranged, with a spectacular view of the river. I would highly recommend staying here.
