Antonio and Maria are really friendly and helpful. They met us late in the evening and answered all the question about the city and places of interest. Moreover, they are always ready to solve problems quickly (we left the keys inside the flat and Maria was our savior).
As we visited Porto in January, it was not really warm in the flat and a little bit moist, but Porto is so amazing that we spent most of the time explorering the city.
The flat is wonderfully decorated and is centrally located, so you do not need to use public transport.
I can defenitely say, that this flat is a great option from the "price-quality" point of view.
