Flat was really nice and modern with a lovely little balcony overlooking the river. Had all the amenities we needed and made the stay very comfortable. Communication was excellent, when we needed a second set of keys they delivered it within a couple of hours. Only slight downside would be the location being a little bit away from the livelier parts of Porto with the only pedestrian way across being the main bridge about a half hour walk away. However, the discovery of the public electric scooters quickly solved this issue and we'd highly recommend using them.
