Perfect for a couple visiting Porto. Excellent location, beautifully decorated, very functional. Very clean, nice toiletries and towels, kitchen well equipped. The little balcony table overlooking the alley was great for morning coffee and evening wine. Sebastiaan is an excellent host with quick response time. He arranged a ride to the airport for us to catch a very early morning flight.
Note that there is daytime noise from construction of a new metro station nearby. This noise is pretty much blocked out if you close the windows. The apartment has an AC unit for when you close the windows.
