It's just as good as all the other reviews suggest: -
a) great location v close to the Sao Bento train station,
b) spotlessly clean,
c) comfortable bed and fantastic bathroom and shower,
d) good facilities (we didn't cook when we stayed but it would have been easy to do so as all utensils are there, as well as some herbs and spices),
f) great communication from Graciete.
If we return to Porto we'll definitely be booking this appt again.
