If we weren't so tired when we arrived late at night to Porto, we would have just found another place.
The apartment is small, weirdly divided and has only very essential furniture. The real issues: it had not been properly cleaned, had visible water damage on some walls near the windows. The toilet seat was broken. The bed is too small, too low and has a very poor mattress.
The location is good, and because it faces an internal area it is relatively quiet.
