The location is the greatest quality of this place, as it's right by everything you need to see in Porto. However, please be aware if you have any accessibility issues that the stairs to arrive at the place are difficult. There is an elevator, but it was not working throughout our visit. As well at night the stairwell is not lit, and we had to use our phone flashlights. As far as cleanliness, the place appears clean but unfortunately has an ant problem throughout the home. Overall, the host is very responsive to messages.
