This apartment is very great : clean, well located and comfortable ! Ideal for a couple, it is five minutes near the Bolhao metro station and it's in the center of the city.
We were very well welcomed by Jose and his colleague who indicated us all the great places to go in Porto.
The services and cleaning fees (50€) are totally ok because there are cleaning woman who come to clean the apartment during your stay and change the towels and the sheets, which is very appreciable !
The only little problem is that the Wifi doesn't work so well but is it really a problem ? ;)
