I stayed at the Almada apartment and I just loved this place. It is super clean, within walking distance of everything and very stylish! The communication with ORM was also spot on - I was welcomed by Alex who had prepared a map with all the must-sees in Porto and spots locals would visit - he was really nice and spent a lot of time answering all the questions (thanks again, Alex and to everyone at ORM!). Also, the optional breakfast was absolutely perfect and delicious and José, who delivered the breakfast every morning, was also really nice and flexible in terms of delivery times. I would definitely recommend this place and will book this or one of the other apartments offered by ORM on my next trip to Porto.
