This is a budget home located in a quiet, residential neighborhood, close to the Marquês metro station (4 minutes), with direct connection to Trindade (metro hub), Aliados (city center) and São Bento Station. (Marquês Square is a little gem in itself - we loved the feeling of coming out from the metro station at night and being greeted by the rich trees of the small park and the Parisian-looking sign of the Pereira Café across the street from the square.)
The home is very well-equipped (including washing machine). It has a lovely balcony (with windows) where you can have breakfast or a late snack at night, a lavish bathtub, a king size bed (which some may find a bit tall and squeaky though), fast Internet, TV etc. It is modern, functional and clean. We spent 7 nights and found it has everything needed for a longer stay.
The windows overlook a closed courtyard typical for older Porto residential buildings. It's really quiet, but you should expect to hear a rooster every morning, starting from about 6 a.m.
We didn't get the chance to meet the host in person, but everything went smoothly, despite a slight language barrier. We felt great in this home and we hope to return.
