I stayed at Icon Duplo Ribeira hotel in Porto with friends. The staff are all super friendly- at reception, showing us our rooms, and at the breakfast area as well. The room temperature is just right, high ceilings, lovely windows, beautiful interior design, very modern washrooms. The amenities provided are all a nice touch. Location is central, walking distance to the water, to the bridge, to city wineries, sap bento train station, and Michelin restaurants. The breakfast that comes with the room surpassed expectations - the buffet was healthy with fresh fruits juices as well as introduction of local delicacies. Fully recommend!
