Catarina’s place is perfect when staying in Porto. You can walk to the historical centre in only 15 minutes, same for the river and all the popular spots of the city.
The only negative note is that the place is not very quite. Unfortunately there was a group of young people in two apartments upstairs and since they were very loud we could hear a lot of noise. Same for the streets noise especially if on a weekend.
But overall everything was good and Catarina is a great host with the best suggestions, especially for food 😋
