This was our first time to Porto and as we were two families of 4 we decided to book a big apartment instead of booking two/three hotel rooms.
The apartment is spacious and split between two floors although there is only one bathroom and one WC closet on the main floor and no bathroom upstairs.
Also the stairs that lead upstairs are very steep and with narrow steps so not ideal for children.
The flat itself is very dated and definitely needs some attention! The shower is in the bath tub and is very cheap and old, the shower curtain is dirty and sticks to you when you shower. There was a definite lack of cleanliness everywhere. The bathroom floor had not been cleaned properly and there were hair and dusts everywhere. Under the beds same story.
We were greeted by the agent(?) Patricia, who had probably never been to the house before. Although she was very nice she did not seem to be very knowledgeable about the flat and its amenities at all.
The other downside about the flat is the 4 flights of stairs that go up to the flat. Be prepared especially with kids and luggage!
We also found that the old nature of the flat infrastructure doesn't help in stopping the noise from the busy roads downstairs and the summer heat, only slightly mitigated by the many fans present in the apartment.
The big upside about the flat is, of course, its location. You can walk to the river front and other central areas of Porto without needing to use the car.
