Very clean apartment and good location, only a short walk to main areas. The pictures do a good job of portraying the apartment although the bathroom was smaller than expected which made showering quite cramped.
Our WiFi wasn't working properly on arrival although this was very promptly fixed by the hosts who allowed us access to the neighbours WiFi in the meantime.
Our main complaint however would be the amount of street noise that is let in to the apartment. Even with all windows closed we were woken up many times by people making noise in the street or with the neighbours dog barking. It is perhaps the price you pay though for a traditional apartment in a busy residential area.
Overall however I was very happy with our stay and would return to this apartment if I was in Lisbon again.
