Very clean place with everything you need. The street is very noisy though and the sound is echoing up even in the 4th floor where the flat is located. Lift was out of order! But the place it is very close to the river and favorable destinations. Not very close to the metro, be aware of that. You walk a very steep street uphill to get to the nearest metro. Service, like getting the key, is done by "Porto Concierge" which were very friendly and helpful. They have an office near "casa da musica" where you get the keys and they give you great infos on the city.
