We enjoyed our stay at Martas place very much. The apartment feels and looks very comfortable and is spacious enough for a long stay in Porto. The kitchen is perfect and well equiped for cooking meals, only an oven is lacking (which probably will be added soon, since the apartment is fairly new.) The location is great aswell so we didn't even use our public transport card.
The communication with Marta was very good and very straight forward. I didn't met her since we self checked in but my impression of her is that she is a very kind and polite Person.
I can wholeheardly recommend Martas beautifuly furnished and comfortable apartment! :)
