We enjoyed our stay here! The apartment was beautiful, quaint and very clean.
The location was great - an easy walk to the Dom Luís I Bridge.
The only two negatives of the apartment were that it smelled of new paint which was a bit irritating at times. Also, we were told we needed to pay a tourism tax, so we did, only to find out later that it was already paid through the Airbnb listing.
Apart from that I would recommend this apartment!
