David's apartment is pretty much as other reviews indicate. It is located in a very central spot. For travellers, it might be good to know that there is a self serve laundry just a few doors down, and a place to store luggage, if needed. The apartment is basic but has everything you need and it was clean. It can be noisy from the street below, so take some earplugs for sleeping. David was very responsive and kept in touch with us throughout the day and met us with keys and tips on Porto. We missed a train and were several hours late. It might be handy to know that the apartment is on the second floor and does not have an elevator. It is not a difficult climb up, but it could be cumbersome for some if you have a lot of luggage. All in all, it was a good stay at a great price considering the location.
